manga inspired portrait

I'm a big fan of manga/anime style of drawing. I used to practice a lot when I was a little younger, watching TV shows like Sailor Moon, Dragon Ball and Great Teacher Onizuka. My brother and I would pause the recorded shows and draw them freehand. It's something that I'd like to get back into sometime in the  near future. I recently did this portrait of my brother in manga style using SketchBook Pro for ipad. I'm a little rusty. It's a little rough but it reminds me of Riley from The Boondocks :)
