Eww. The color combo hurts my eyes, and why tf is the circle not centered? (ok I checked why and I'm not convinced.) 
#Belarus
Kinda cool, but only because of the decorative woven-looking thingy on the left (yes, I know, *hoist*).
Colors hurt my eyes a bit though. 
#Bhutan
Really cool. Unusual color combo, and awesome dragon tastefully following the diagonal. Nuff said.
