I think it's a pretty cool wallpaper. You don't see many Heine fans.
Adding a quote from hin somewhere in the middle would be nice.

Yeah I really like it.. you did it well
with the brushes on the background..
good on you..

Well, nicely done, but could be better either with a contrasting background or one more similar to the one of the scans.

Yay a wall of Heine. I like him...despite his character going to waste...darn, why did Fukuda and them kill him off? *sigh* anyways, to the point. I think the scan of Heine is too far to the left. You probably have your reasons for doing so but I'm just saying that he's so far to the left that it feels odd when I look at it. The centre of the wall doesn't have the "most important stuff"...if you get me. I know it can be to either side, but not too far though. Good job with the bg though. =D

Wall is cool but it I hate the fact that you used Heine, he died so quickly in the anime.

Hi~
Nice wallpaper!
I think the background is all right since it matches the colour of his mobile suit...more importantly...
it also matches the character on the wall...especially, the colour of his hair^^
If you put a black background on the wall...of course the mobile suit will stand-out automatically, but the uniform of the character will be camouflaged-_-
However, if you put a white background in alternative...the wall will become so plain~which is not very good since it emphasizes the present of his mobile suit more than the character><
In general, Well done.

Wow!! Finally!! I can find Haine-sama wallpaper here! ^_^ I like the bg, cool abstract bg, and It looks fit well with the mecha in the right! Thanks for sharing it! ^_^

GOOD BUT THE BACKGROUD IT WILL LOOK BETTER A LITTLE MORE DARKER BUT STILL GOOD
