the colour count was waay too much for the weekly but I wanted to post it so yeah,hope you like it.
The pixels in blue are on the way
I agree with Reo, color management is a good skill to have and this would be easy to fix for this piece! Probably the piece would look even better if you did it with 12 colors!
I think it is very possible to do this piece in 25 colors without any noticable loss in quality. Combine some of your greens!
