I envy the skill involved to make this. I am a big doctor who fan and I adore David Tennant and you have really done them both justice. You have captured his face picture perfect. The bit that I really love is the hair, it looks so perfect and wild. I like the choice of background, going simple was a good choice, it really brings the focus in on David. I think its good that you have drawn him serious, because most artists when drawing David seem to mostly draw the fun crazy side of him, but I love how he has the ' I destory a planet with a click of my fingers look ' and you have made him look powerful. Really really love this piece. Certianly one of the best I've seen on this site. My hat is off to you.
