Starting out

[Basketcase]

I like it. But I'm not feeling the dithering on the shadows. You're got a bunch of middle greys, use them to smooth the transition.

You're also using a loooot of colours.

Why no black outline on the bottom of the table surface? I know you can make those pillows more puffy.

There's a few weird things going on with the shadows. First, the table's shadow makes it look like the light source is directly above its front (blue line), but the light from the monitor should pass under it a considerable amount (red line), seeing how they're on about the same level. So the shadow from the table should start at the green line, and the legs should have shadows that extend to that point. Also, the angles of the light coming from the monitor are inconsistent (picture at top right). Either make the left one completely horizontal or rotate the right one out a bit. And there should be shadows on the back corners of the table.
