AH gorgeous wall, I already said on MT that it is awesome! You made great job with vectoring and painting, your vectors have your personal style, keep it up!! ^^

I'm not a HUGE fan of generic vector walls, but i do know alot of good examples of them so i'll give this the best critique that i can even though i have limited experience i guess

firstly, the colors really make generic vector walls, they should be bright and the shadows need to be chosen right. i think her hair's base color is too dark, and the skin's base color is too saturated. that combined with the shadows being too yellow causes the skin to look.. well not as good as it could :D. remember to change the hues of your shadows to give your cellshading depth since you really only have two colors to work with while trying to "trick" the viewer's eyes into understanding the mood

lineart is decent, though for her hand being so close to the foreground i really think they should be cleaner , same with the hair--remember with close ups you have the advantage of not having to slave over the bg, but you do have to concentrate on the details of the foreground more.

blush is not correctly placed, it should be closer to the outer, bottom corner of her eyes and darker at the top. more gradiented and faded at the bottom. ideally you would use two or three colors to give good depth

lol, long post--and i do realize this was just a shotgun wall, but a few more minutes spent on choosing the right colors i think would have made this wall alot better >D

The most important key in making a simple wall is to make it look like it wasn't simple and quick. This looks really quick, like you didn't even try to fix anything, I see many broken lines and in some places the hair looks cut and didn't quite make it to the arm. Also I see the outline going over into the skin, and in fact the outline is very messy and pointy in some places. I think the colors are too dark for her, something much lighter would've done better. Pink and yellow maybe, her room is too dark as well. I see one color leak, on her foot.

As for the bg, too smudged. You over smudged it, you can see on some places it's blurred and smudged where it shouldn't be. The bed's outline in back is blurred and that wasn't needed as well, also the sky looks weird...just some normal brush clouds could've been better.
You didn't line her hair which I see messed you up badly since it doesn't flow like hair should, rather it looks boxy and pointy.

So altogether, the color needs to be changed to a lighter tone, the sky could use some changed, use a nice cloud brush or just make them yourself. Alot of adjusting needs to be made for her, and yes as Vitaa mentioned her blush is too close to her nose, move them more to the outline.

Nice wall, I just think it needs more time in PS.

Your vectoring style starts to be similar of mine. Change of style due my greatness on CC?
Lol j/k. Anyways Kotegawa looks pretty good on this one and goes for the whole composition.
Great gift for our Cy.
