This doesn't alter the fact that they are extremely impressive. How long do they take you to finish?

Eh, about an hour and a half to two hours, depending on how distracted I become and how much detail there is in the piece.

Been thinking about doing it with musicians and celebrity icons as well, but I don't have as good a sense of the person.

Have you considered doing something like that in oil to capture the mood of a live concert? The lights, the haze and the excitement probably could be obtained through oil.

I find I'm not very skilled in A) colour and B) paint. Granted, I don't practice either much because I don't find them enjoyable (I become quickly frustrated and abandon whatever I've begun). I've done two colour pieces yet that I think were worth the time it took to create them.

That's a shame. Definitely worth it in my opinion.
When I get the time, I think I might try and use some oil on canvas or something to try and capture the mood at a live performance. The idea seems to appeal to me.

Well you seem to be good at monochrome painting. Maybe experiment with that until you are more comfortable with many colours. Worst comes to worst you get even better at what you are good at now.

This is true. I have a hard time with paint though, because I work sporadically, off and on a piece while doing other activities over the course of days, and there's so much cleanup involved with it that it's not really worth it unless I'm going to sit for hours at it. With pencils and pens you can just toss it all in a bag and clear it off, but there's a lot of maintenance with paint.

Ody, one collection I do have is a gigantic pile of awful drawings from since I was eight.

You should scan them. We would like to see them.

Sure, if you're in the mood for some cheap amusement.
