Wow! I'm jealous of how fast you were able to switch from your style to a semi-realistic, line-less painting. I've been trying for awhile, but I can't quite get it...Anyway, before I get into specifics, I'll really be looking forward to see what you do with more human characters like Seir or Josh and Damien, because your technique here is pretty interesting.

Love:
-Skin shading. You can really tell that your light source is above her and the shadows are consistent with that. I love the depth of tones in her neck...They give it an awesome shape and I can't stop looking at it KD Your highlights are consistently strong too.

-Loose hairs. I think that adds so much to the "realistic" factor and gives her character, too. They look soft and in all the right places.

-Nose/eyes. Fantastic shape and shading on the nose. I would say it's a little long for a person, but she's not really human - that's part of the reason I'd like to see some other characters from you X3 The "semi" part of the realism comes through in her eyes. I adore her eyelashes, though they are a bit thick - and I especially love that glow. For next time, the glow in her eyes may produce some more light on her face of a similar tone. Also, depending on the depth of realism you want to obtain, some tear ducts in her eyes, even teeny ones with a hint of color, would add.

-Overall character design. I love that color scheme and her skin and just 8D Ah. The background color blends well, too. Between her fabulous eyebrows and neat facial markings, you have the makings of a great character.

Some things to work on:

These are really just nit-picking things about the overall piece, less about semi-realism...The only thing I would have you consider about her is her hairline. Her head is really long and her hairline is really high. I don't know how the character is supposed to look, but depending on what you do with other characters, you may work with that some. Her neck is long too, but I kind of like it either way.

This was meant to be a headshot, but her hair extends past her neck and that breaks the illusion a bit for me. Cleaning up the edges around her neck may help with that - or for next time, you can always extend to the edge of your canvas. Or just shrink your canvas X'3 Centering her may also help with the "just a headshot" illusion, but since she is off-center, it really feels like she should touch the edge of the image.

I...Think that's all! Overall an awesome character and a fantastic transitional piece to semi-realism.
