Senaka

The title is blatantly ripped off one of Majo's Xel/Fi Slayers pics.^^;;; ("Senaka" means "back" in Japanese. As in the human back.) But of course it has nothing to do with Xellos, or Filia, or Slayers, because that would be stealing someone else's idea, which is icky.
...Anyway, this is a very random Sentinel pic that was surprisingly easy to draw (maybe just cuz I draw Sentinel all the time^^;). The position is a new one, so that was the main challenge. He looks slightly different in this one compared to my other pics of him... I think it might be because of the expression. He looks older, no? And all things aside, I'm kinda proud of this pic.^^; A very rare thing for me.^^;
