Crimson CafeThis url leads to the main site where he has other images sometimes and if you click the top left image/sprite on the menu frame it brings you to a page which you have to scroll down and click another link. Then you can view a bunch of sprites they have done too, dating back quite a few years.
Akemi's WallpapersThis person makes some really awesome tokusatsu wallpapers. Again it dates back a while so quite a bit to check through.
I don't like that alpha-vector guys deviant art. He does a good job on some of the icons but some of the fully custom stuff looks kind of rushed out. I looked a bit more and the guy charges for it too. Nothing much, but it reminds me of MW2 10th lobbies. People paying even a small amount of money for something they shouldn't have to pay for in the first place just so the guy makes a little money off a side hobby.
Fun image to end post on:
