Go Spine Go

So I've been working on this thing for some consecutive hours. I dunno anymore. But as of posting this it is 6am and I haven't blinked in like 8 hours.
I think it is actually my second ever digital painting? The first one I did last year, and it incidentally was also The Spine.
The reference photo I used was just one that I took at Anime Midwest this year... which was when he screams and kind of powers down for a second during Go Spine Go. Hence the title. :U
so there is that.

I also posted a WIP type deal, which can be found HERE if you want to check that out.
