The speedpaint makes this look so easy. . . but then I think about the time involved, not just in this, but in polishing your skill to such a level in the first place, and I can truly appreciate how awesome this (and your other cubes) are. :>
I appreciate the novelty of the song choice, but the video goes by so fast I can hardly register what's going on. Any chance you could upload this one with a longer time lapse so I could get some insight on your process?
