Of course it's ok. Grayscale is fine. You might try fewer colors though. Maybe 6 or so to start. Practicing Line art or complete forms is fine.

But off topic, this week was adventures in digging.
There is a tree stump in my yard. So I go to dig it out. Only it's not a tree stump exactly. Two feet down and there's no roots so far, just trunk. Like the previous owner buried a tree halfway and then just chopped off the top half at the new ground level. Why?
This thing could go down six feet or more. Well, ok, I can just cover the top with brickwork.
Digging adventure #2 was the anvil. Yep, my house came with an anvil. An I-beam really, about 1 foot long and 6 inches in either direction. Welded to a short post that is stuck in a large post that is stuck in the ground. The whole thing comes up to your waist. The anvil part is heavy, gotta be 60 pounds or so (25+ kg) but it comes off and I can carry it. The large post goes down to the ground, embedded in concrete. No problem, I can just dig it out, right?
An hour later, I've got a hole a yard deep (1 m). I've had to dig a hole to stand in just so I can dig down further. The post keeps going, and doesn't even wiggle when I tug on it. On the one hand, it's kind of amazing how much dirt one person can move in an hour. On the other, I'll never be a gravedigger because I'm too much of a wimp. And the post still mocks me. I'll give it another shot tomorrow.
Anyone have a use for a heavy chunk of steel I-beam?
