INCREDIBLE!

First off, it's spelled Heroes not Heros. Secondly, I'm surprised at the feedback because I think this wallpaper looks bad. Now let me qualify myself first, before I start a fanboy flame war. The wallpaper just has too much text stuffed in all the nooks and cranies, and I think this is something that really degrades from the wallpaper's style, because I put a wallpaper on my desktop to look out and not to read, so the fact that there is so much text all over the place makes it seem a little schizophrenic and cluttered. Third, the characters are shaded with two colors: black and white, and while there is nothing against using these too colors, they need to be used in moderation, for an entire wallpaper like this with it just makes the colors mesh into the point where they become incoherent and indistinguishable for me (i.e. where is snake's left side of his face?) Then I remember that this is a tablet sketch, which I give you full credit for, because for what you did it is amazing, but in bringing it over to photoshop and the other tools at your use, you shouldn't be afraid to add some color, especially if a lot of the shading is going to fight with the character outlines for supremacy like with snake's face, which tends to be the focal point, and when the focal point is confusing and displeasing to look at the wallpaper losses credibility. This is also where the words in the background fight with snake because a sketch with a load of words, which inevitably are covered up or at least cut off by his head essentially defeat the purpose of them. The words just take away from the sketch in that the sketch style and then the very acute lettering fight because of their differences like the French and English in the 15th century. So what am I trying to say in conclusion? Well to sum it all up I think the wallpaper is bad. The random blobs of shading which I presume to be blood, meshed with the shading and outlined characters in the two generic colors of black and white where the only diversity is in the tone of the black used make for something that seems like pencil meshed all across my screen in the end, which does not make something enjoyable for me to look at. I'm sure others will disagree and that's fine, but these are my takes on it. I commend you a lot for a great sketch, but the absence of color really defeats it as a wallpaper, because a color-less sketch is fine for something like Deviant Art, but on my desktop I do not particularly take a liking to it.

Great as an art piece but not so good as a wallpaper. Some blank space would be nice. Not sure about the typeface on all those 'blurbs' there, I'm not an expert but try something without serifs and see if that works. Nice signature.
