Matt Bellamy portrait

Another drawing of Matt! I love drawing him! I don't know, but he has something special in his face that makes me want to draw him again and again! The worst thing is that I made a huge mistake in the background and had to erase it...and that is the result. I may try to fix it, maybe a flat background would be better. Can someone advise me, please? This is a present for a friend of mine and I want it to be as perfect as I can.

Otherwise, the reference photo was from when he had blue hair.

This was done with 2B, 6B and 9B graphites. Reference photo [link]
