Iwan Rheon - Colour experiment

So I've never been able to use colour all that well, but I've been seeing a few really good portraits in colour recently and decided to give it a shot. I only did it in my a5 sketchbook, thinking it was only a doodle, but it turned out a little better than I thought It would. Maybe next time I'll switch to a4.

I need better/more pencil colours though I think yet. It looks better further away and in person than scanned though
