Interesting design. Your gryffon doesnt look like most others I've seen so far. It's propably because of the main body and the back legs+tail. They remind me of a ferret or a wolverine which gives it an interesting touch. The colors are really well chosen and it's surprising what you can do with so few colors. Good job there. A point of criticism are the feathers and the composition. If I see it right, you used one feather over and over. If one is on the front and one on the back, this doesnt matter, but if you have four times the exact same feather on one side, it starts to look odd. You could really need a little variation there, so that they're not all the same color, form and pattern. The composition looks a little boring to be direct. I think it's because there are no overlapping forms and because you place everything to balance out everything else. How about just one feather on the back ? Not neccessarily in the centre. Or two feathers overlapping ? I just noticed something else what looks a little strange. The form of the gryffon looks like it's saying: Whoops, end of the shirt ! If you get what I mean. I still think it's really nice, but it can definetely be improved. I hope this helps.
