Maybe not your best work? It’s ok though.
I’d suggest turning the brightness down. It’s too bright, and it might cause headaches, possibly seizures...
In fact, it’s so bright, I can’t even tell if that’s a tooth or a part of their skin... And the background is too hard to see. So improve that ok?
That’s my criticism for you. The art was good though, and the lack of lines were pretty well used.
Overall, could use improvements. Good luck on your future art, you might need it.
