Is that the Guren S.E.I.T.E.N. in the background?
If it is, kudos for another Guren wall! Your wallpaper has a nicely-blended color scheme so I'm sure it'd make a great desktop. As for it being a Guren wall (I've overjoyed and I don't mind more of these but) the motion blur is a bit awkward (maybe you could lessen the motion blur on top of Guren and increase the motion blur below so that it looks more like it shot out from the ground?) and I'm not quite sure with how you illustrated the depth of the scenery that lies before your Zero vector; needs more gradient shadowing and blending to me, or perhaps a texture overlay to screen out Zero and add depth.. Also, I notice the clouds are a little grainy/noisy and the text seems a bit too plain and in-need of some effects~ Anyways it's a nice scenic wall :)

Well done , the idea of the wall is good but i guess the BG doesn't fit to the characters

Looks nice, but lulu's vector doesn't really match with the backround perfectly ^.^"

Marvelous!

Remove motion blur from Gurren -> Awesomeness.

Kakoi~! (*-*)

Nice style and concept. very good.
might a suggest if you change the gurren to the flying fortress "key of damocles"
it'll have an aura where in zero is targeting or clinging to the key of damocles
before battle. Just a suggesting friend. |
but overall nice design bro!
