I might have called this finished several thousand tiny brushstrokes ago, but as ever, I needled away at inconsequential intricacies probably nobody would notice or care about. It's always the process. Being lost in it is something all artists are keenly familiar with. Botlickers don't get it.
Detail from the same painting of the fairy wren as in the quoted posts, showing the bird's legs and lower portion of its body. The feathers are many shades of intense blues while the legs are a bluish, brownish grey. The piece is very small and very intricate.

This #Etruscan terracotta votive portrait head of a man is clearly modeled on a real individual. It was part of a votive deposit associated with the Manganello sanctuary in Caere, where people went to pray for healing or thank the gods for recovery. 🏺 1/ Late 2nd-early 1st c. BCE. 📸 me
A male terracotta head with reddish skin tones and residual light pigment over the hair, giving it a grayish appearance today. While initiated from a workshop press-mold, the facial features were heavily hand-modeled to achieve an intense, personalized verism: a high, deeply wrinkled forehead, an asymmetrical aquiline nose, pronounced cheekbones, and prominent ears. Rather than a generic archetype, the piece functions as an authentic individual portrait, likely offering the specific identity of a worshipper to the gods. This refined image attests to the skills and expertise of its sculptor and painter that could artistically rival any Greek or Roman counterpart.

And, yes, people compare him to former US Vice President Mike Pence all the time.

Just discovered some recent beaver activity and several beaver dams. There are only very few and very fresh bite marks, and a few very old ones, so I suppose this was a rather recently repopulated habitat.

Today I visited this awesome lake in the Chiemgau Alps of Bavaria. The weather was rainy but the colours of the water still incredible. I could see a few rainbow trouts, some brown trouts and a single char of unknown species plus a lot of minnows, and as an ornithological surplus also a merganser.
