Unfinished projects and interview

Just a few years ago, my main reason for drawing was so that I could ink and color up my doodles all nice and pretty...I'd rush through the drawing and leave in all sorts of crappy mistakes figuring I'd just cover them up with a clean line and nice photoshop colors. Nowadays I make tons of plans for art projects, but I'm just too lazy to ever do anything with them. This is the closest I've come in a long while to a finished drawing.
A couple weeks ago I became overly excited about Rex Hackelbergs paintings, and decided I would try to be like him and start some new projects that I could be proud of. I drew a whole stack of hillbilly girls with the intent to paint them up all nice and pretty, but as it turns out I still can't paint, and these still aren't going anywhere.
Some more drawings that I planned on inking up all fancy-like. I was going to learn to use the brushes in photoshop to color them...but everytime I sit down in front of the computer I end up stalling or suddenly remembering something "extremely important" that I have to do and go running away.
On a happy note, here is something from a project that will actually get finished- and it's not girls! A couple layout poses from the Weird Al video:
So anyhow, where does this overwhelming feeling of obligation to finish drawings come from? I'll admit I love a beautiful painting or carefully rendered drawing, but often I enjoy looking at a rough and dirty sketch just as much, especially since so many finished drawings lose what makes the original drawing look interesting. It seems however that a lot of people greatly prefer a finished drawing. I have been told in more than one email that cleaning up my drawings would make me seem more legitimate. I suppose that's sort of true, but I'd rather think that I'll become legitimate when I learn how to draw as well as the people I look up to. Maybe I'm just making excuses because learning how to paint seems so time consuming, ha! I think this sort of thing isn't even an issue for people who are actually able to get the spontaneity and energy of a scribbly drawing into their finished artwork. There are people out there like this (you know who you are), and I curse you! Actually, I want to be just like you...anyhow, this is turning out to be longer than I intended.

It's really long though, so watch out!
