Hmm i had expected such a wallpaper from you but you messed up a little :P
Its a great background perfect for such a wallpaper.The sketch is amazing with no jagged line or anything.Very clear and an amazing idea.Now the thing that messes up the wallpaper IMO is the over-crowded swirls here and there also the Original Art text and the text above Animepaper.Now seriously it really makes your wallpaper feel bad.The thing is your wallpaper is a focused on simplicity,the text hover focuses on graffiti which does not belong in a simple world.It makes your wallpaper go to the grungry type of side,yet it is not made in that sense.All My Body is Clear text and the japanese text under it looks marvellous also the other text the quote.Another thing which doesnt go with the wallpaper are the cubes.If you look at it closely the cubes do not look good especially the smaller one.The smaller ones perspectives look kinda odd.After looking at those power ball that are blue and glowing,it seems as if they are meteorites and they are raining down the cubes *lol*.
My idea of how to get this better:
Hmm well you could have used a 3D heart or something inside the body to make your idea even more perfect.Then it would look like his Body is really clear and you can see his heart :) even if you dont some other swirls would have done the job but in a less quantity and in an order in which they wouldnt look over-crowded
A problem in the sketch?!:
Yup,his foot.The one that is below the other one.The one below which the text "All of my Body is Clear" is written.That doesnt look like a foot.U gotta do some thing about it
I hope my comment has helped you in making your wallpaper more outstanding than any other wallpaper
