Well... I do like emo music very much and no my hair isn't dyed black >.>
I don't really like Fall Out Boy and especially their new song, so the title is less appealing to me... even though the title is really well made!
But the dark feel that this wall give is a big plus! You don't find many Bleach wallpapers with this kind of atmosphere and this just gives it some more variety.

There are some minor things... like the faces of Ichigo, Renji and Ishida's. Rukia's face (or is it Hinamori... I can't really tell =X ) is done well, her white skin just gives the contrast to all other dark collors. But the other faces are way to dark and to smudgy (did you aply the cloud textures also on their faces? ) If all the faces were collored like Rukia's face is it would be a big improvement. Even though I like dark wallpapers a bit light spots just gives the wallpaper more contrast.
Another way to get more contrast is to make the stars on the flag a little brighter. But what is that flag doing there in the first place or does it have a special deeper meaning?

Anyway the result looks good and just keep on practicing and keep an eye on the contrast!

A truly original wallpaper and I haven't seen that in a while.
It's a really simple concept but the textures made it really have sometime... dunno the words... just make you wanna say: Wow...
The thing I have to add isn't really necessary but I think it would look a tiny bit bitter. The way the wings are collored and the girl itself makes you focus go to the wings, but I think the focus should be on the girl (is it because I like girls so much...? ) So if you had made the red in the girl a little bit redder and less fade out or a little less texturefull (again don't know the words) the focus would be all on the girl and give it some more contrast.
But it's also fine this way.

Just an astonishing job!
