Hi Snowdog -- I like your "invasion" piece.

The ideas I had was doing something with the round front door/cover which is partially open...I'm not an expert here, but although the door is flat, it seems "too flat" if you know what I mean, like perhaps if it had a bit of thickness and slight beveling for the edge around it it could look more dimensional. Perhaps a bit more contrast also between the ipod and background.... Another idea might be to add a bit of highlighting, in a subtle way, just so the plastic door has a bit of smooth semi-gloss shine, say on a forward edge, maybe a slight gradient change in tone as the door receeds away from the foreground. I don't own an ipod so I can't say more than that about it's structure.
