Please give constructive criticism. It is far beyond just, it is nice.
Think of these while posting here:
What made it nice, the colors, the picture, etc?
Originality, think about if you have seen this before
Creativity, think about this as well
If you're a signature and avatar artist or painter please comment on:
Technique
Originality
Creativity
Color
Blending
And of course remember to tell them how you feel as an artist
This is just a suggestion, you don't really have to if you don't want to.
But it would be nice.
