The next release of Ballistic's Expose series (number 7) looks like it will be jammed with inspiration for both the 2D and 3D digital artist alike.

Looking at works like these below and more, I am sure I can do better over the weekend with mine.

Oh and the 2D cover is gorgeous:
There are plenty of categories though - check out these amazing images:
