A few months ago I uploaded the first image of Robin; today I bring you a reference sheet.
You might have noticed two things:
1) Some colors are separated from each other (that's because I used markers to get the colors I wanted)
2) The eyes (it's a little experiment that i'm trying out and might fully adopt, since I find it easier to draw this type of eyes)

In conclusion: Changes will definitely be made in the far future, but this is a good way to start. And I'm happy with how it came out!
