I'm sorry to be rude but you're taking officially released images and putting a little facade on top and putting it up as your own artwork? What gives?
I have actually been doing this style of fan art for 10 years, crediting original art sources where they are. Those pics above are from the presskit. The facade/bars I've made and used in diablo 3 wallpapers for more than 5 years. Tweaked and adjusted. The class icons are from the website anyone can see and use.
I take credit for the wallpaper, not ALL of the artwork in the wallpapers.
