Hi Jill. Sorry about having to delete this before. I really like the way you've drawn the purple guy (sorry I'm unfamiliar with Yu-Gi-Oh). He reminds me of Jack Nicholeson. I keep wondering what your mistake was. Is it that you forgot to do eyebrows?
No problem about the delete. I probably should've read every thing but anyway the mistake was that I accidently drew a sixth finger on the green guy without noticing. Silly me but thanks for the comment!
