Everything looks fine to me. It suits the mood and feel of most of the characters that you've drawn rather than super bright and vibrant colors.
Thanks all. Guess I was worried for nothing.
I haven't thought so.
Can you elaborate a little? I'm pretty sure my answer is no, but I want to be sure I know what you're talking about.
Just visually, I wonder if my work is too hard to see, tough to make out, etc. Differences in monitors and all that.
