Looks clear enough to me, unless you're talking about the background, which doesn't really look like anything. I also like your shading, but some smoother edges on the apple couldn't hurt. Adding a background that actually ties in with the apple would probably make it even better.
“Rise like Lions after slumber
In unvanquishable number.
Shake your chains to earth like dew
Which in sleep had fallen on you—
Ye are many—they are few.” — Mary Shelly
