Despite giving you a challenge, that Ventus looks actually pretty nice since you got so many details right. ^__^
One small thing you forgot though is the keychain with the green gem between the two feathers on his Keyblade.
Compared to Roxas I can imagine Ventus more challenging though due to his somewhat weirder outfit. Not only has it much of extra stuff like the chest-straps and armor pieces, it also has three different layers of clothes (black shirt, silver vest plus the black/white jacket with the red collar).
No question though I dig it very much, also when considering you do this all with freehand drawing. You sure have talent.
I think the "problem" with his nose stems also mainly from the eyes being too small because the ratio between them is off. The nose only "looks" too big in relation to the eyes.
