This is a sequence of Trunks in a DBZ episode.
I recently saw an AMAZING documentary of a short film called Little Witch Academia by Trigger. I highly recommend you watch it if you are into animation. --> LINK
I also wanted to at least show my appreciation to the animators by watching the actual short as well :D I have to say that initially it looked like something I wouldn't watch, but I really ended up enjoying it..especially the animation and draughtsmanship is outstanding. Below are some sketches of a couple of poses while trying out some different media to give it a lick of quick color.
I then switched to watching a few episodes of Kill La Kill by the same studio. I was totally amazed by the VERY STRONG POSING and EXCELLENT SHOT LAYOUTS. It's quite incredible and I highly recommend it just for that. The story itself could be a bit offensive, since you get arse and tits shoved into your face every other second.
