Why thank you very much! Since you seem to enjoy these so much, you should check out Sapphire1010 's art on her profile or her tumblr, linked in the description! She makes a lot of awesome work, and if you really like something of hers and want a wallpaper made from it, let me know!
They do definitely make good wallpaper subjects. A cool vision would be to have a propaganda poster style with the three main human wonderbolts looking heroic while jets are flying above them. That would look cool with this human look to them.
