I'm tempted to say mushy cute things...^_^; it's so sweet! I think something that may be throwing this off is the hands-the knuckles don't line up properly, and it changes their structures a bit. If you want to bring out the hair more, try adding making the shadows deeper.
Today I tried to reallign the knuckles, but I'm not home to scan and reupload. (I'll rereply to this when I have, so you'll know. Frankly, I didn't really notice the "not-lining-up-properly", even as I was editing it, so I don't know if I succeeded in fixing it.) I also changed "my" eyes, so I think they're a little more even now. I also darkened both hairs a BIT, but I don't want to darken Chella's too much because I want it to be distinctive compared to mine. >_>;
I love mushy cute things, so thank you! xD In fact, thank you for everything about your comment; I really appreciate it!
