Very nice wallpaper , i like the wallpaper but i guess the texture isn't looks goood..^^"
so i'll favorite it for your hard work.

Lol personally i dont understand the clash between vector-wallers and extraction-wallers, if it even exists, since my feeling is really that both can be executed nicely and both can be executed poorly. but, well all i'll say is that people dont vector because they think extractions are inferior, they vector because it gives them more fluidity with the image...
that being said i like the composition of this, but the lines in certain places exhibit some artifacts that i feel don't blend with the texture of the bg that you created
and well, yes the blue lights need to go 1)because they seem rather last minute and lack detail (only one color on blending mode without shades) and 2) the shape and flow are too much of a break from the fabric of the bg.
but either way i love the concept; the way the bg bends and how the character fits in.
