Tida tida tida your vectoring is rly improving :D
theres jaggies in your vector though (especially around her face), me thinks that if you did the char without lineart it would be better. but i rlyy love her clothes x] and plants are nice to :3 add more pretty clouds in like the scan! lol
awesome job ;D

This wallpaper really caught my eyes on the Home Page. Yeah, maybe is not perfect - the parts don't merge well with another, but the overall looks very good for me.
There is a simple problem - i don't have a Widescreen, so side-cutting again...

The character size vs the grass...well, it's a little odd but i don't mind that. xD the grass is quite nicely done, but i think i'd have preferred the flowers without the white outlining and for the flowers and grass to be more...mixed together, if you get what i mean. the clouds are on the fuzzy side for my taste (me likesh fluffy clouds :P).

on the whole, the character vector is good, but there are a couple of things i thought i should point out. highlighting in white (jacket, hair) is not the best look. with a light color such as yellow, it's acceptable, but with her hair, seeing white so starkly against the darker purple made me do a double take. in addition, the shading layers of her skin are too orange -- seems rather like you used blend modes (soft light/overlay/something like that). the colors are a bit unnatural. and a finally little thing: i don't know what happened with her ear but it looks really grayish to me. o__o

don't get me wrong. the wall is nice; i just feel like there is room for improvement. :3
