Hey! I make art, that's pretty neat. But yeah, I don't think very highly of it myself, and I don't think I've received proper criticism ever before. So, if you have any constructive criticism for me about any of my artworks, please feel free to criticise all you want - even if it is not constructive.
Quick Note: The dimensions of each artwork were too large to fit on the forum post, so the links are there instead so that you can view the artwork in its entirety.
Lovely work! I especially like "Prompt: Crystal." Very nice colors, charming and whimsical.
Constructive criticism would be that your proportions on humanoids could use a little work here and there.
