Since stumbling upon the "speed painting" genre last week, I watched a lot of said videos, and (as with all nifty things I see) found myself wondering if I could do that. As Karen was out of town and I was bored, I decided to give it a try this weekend. I doubt it qualifies as "speed painting" — it took just under ten hours, split up over four days — but since it's the first time I ever tried to use The GIMP to paint something entirely from scratch, I'm not overly worried about the time.
I didn't know what the hell I was doing; it took me a couple of hours to discover that using a paintbrush in "darken" or "lighten" mode was a lot easier than selecting a color, overpainting and then blending.
Anyway... click the picture to see the video (about four minutes long; turn your speakers down if you're at work, there's background music):
Hands are a bitch to draw, let alone paint; perhaps my first attempt should have avoided them. I am somewhat mystified that the hand which was obscured in the source picture actually turned out better in my painting than the one which I could see.
