Anyone have any fish field guide recs? Been having fun going through my trove of aquarium pics but would be nice to learn more about the fish. These are all pacific reef fish i think, mostly puffer/box fish family #art #sciart #sundayfishsketch

More #riso test prints. Trying to print up all my central park pollinators. I didnt draw these specifically for riso printing so the cymk ish separations have been super fiddly. Using blue, yellow, fluorescent pink, and brown inks #sciart #printmaking #art

Hi #PortfolioDay I'm a freelance science and nature illustrator from New England. I love drawing native species I find on my walks, especially if they're weird and warty. Dream job would be to work on a non-fiction picture book

Had a great time sketching at the new york aquarium the other week. Could really only draw the sleepy ones while I was there so I maxed out my phone storage with reference pics and had fun with posca markers at home. #fish #sketch #sciart

Another #pollinator closeup. This time a cabbage white butterfly. This might be my favourite flower in the series, and I had fun sneaking my friend and their dog in the background. #SciArt #art #bug #butterfly #InsectSky #botanical

Really big lichens or a really small hiker? I’ll let you decide #illustration

Be working on this one for far too long but I present to you "Central Park #Pollinators," based on bugs I saw in the park last summer. The plan is to print it as an accordion book but it also works as a big ol sign #sciart #bugs #invert #art #centralpark #botanical #procreate
Spicebush swallowtail, common bumble bee, cabbage white, and European paper wasp, with scenes from central park in the background Euro paper wasp, hover fly, and monarch, with bethesda fountain in the background Monarch, american lady, two-spotted scoliid, and green sweat bee, with bow bridge in the background

Fantastic ending to Baroness Kidron's speech in the House of Lords yesterday, which led to the government's defeat on AI & copyright. Speaking the UK's creators: "Their property, their labour, is worthy of your protection - because apart from anything else, it is not ours to give away."

Folks call your Senators now!! A ban on any state laws on GenAi for 10 YEARS is gonna do unthinkable harm! For those of you wondering what to say here are two posts you can use to build your own script (use alt script to cut and paste) Need to find your representatives? Here you go: 5calls.org
User Zachary Berger recommends the following script: "I'm a constituent in the congressperson's district.
Al regulation is life or death for a lot of the Congressperson's constituents in creative industries, please make sure the section in the budget reconciliation bill banning Al regulation doesn't pass."
User Karla Ortiz gives information on the bill so you can point your senators where to look: 


Call your representatives! Tell them just yesterday (R) Congressman Guthrie added a new text to the Budget Reconciliation bill to BAN GenAi regulation in the states for 10 years!
Hell, point
them to the specific section:
TITLE IV-ENERGY AND
COMMERCE (Part II: Al section, (c) moratorium)

So excited it's vernal pool season again. Eastern red #newt and some of my favourite moss and lichen (Peltigera) I've seen in Vermont. Original digital illo and #riso print, using my own funky spot colour separation. #sciart #lichen #illustration #art #nature #procreate
Original digital illustration. The lichen is definitely a Peltigera, inclined to neopolydactyla cause it has some pretty long rhizines vs polydactylon, can post ref pics if anyone wants to help idRiso print, using blue, orange, and yellow. Orange drum was a lil broken so got kinda stronger than expected but I kinda like the warm vibe.

More #riso prints from my #lichen close ups series. Both from the genus Cladonia, the one that looks more fingery in the sub group Cladina. Fun fact the tips are dark with the same melanin pigment we have as sun protection for new growth #botany #art #sciart #printmaking #illustration

One of my favourite illustrations from last year, showing fish I saw on a trip to the new england aquarium. Originally made it for a two colour riso print but have had fun rearranging bits for some mock editorial layouts. Need to draw more fish #art #illustration #fish #aquarium #editorial

Slowly migrating over. Stupid obsessed with #lichens so starting with a #riso print from a poster series I did last year of lichen close ups. This ones the tip of a Cladonia squamosa branch. In theory they look like dragons? #illustration #scienceillustration #botany #art #procreate
