You're not a speck of Dust

At first I mistook this little spider for a little ball of lint. Then it moved. So I put it on a piece of paper and photographed it.
Good excuse to use my new macro lens.

I am looking for a bit of critique on this, even though I already kinda' know what I did wrong. It's right front leg is more in focus than it's head, for one. Also, I tried the idea of over exposing a white background so it's all white, but that still didn't quite work because you can still see the texture of the paper (that's just regular cheap copy/printer paper).
