Kaioken was always one of my favourite transformations from Dragon Ball Z. So I really wanted to illustrate the awesomeness of it. I only used shades of red for an interesting effect. And I went through many different attempts for the background before I got to this one. I'm really happy with it. The "lineart" that you see there is actually just my sketch. I liked the impression it gave me.
This is the first piece I've posted in a while, so I hope you all like it.
PS: Yes, I know it looks like he's taking a major dump.
