I think you should change the taskbar.
It's way too vibrant
Also the taskbar's studs that poke out, should be really, REALLY less. like don't make it jut out that much.
EDIT:
What about the task bar is just I straight line and not like weird like that. And the start menu button is just the word "START" in that blockland font :D
Maybe have it where instead of studs being going up, have it where inbetween the objects in the task bar(like on that it would be Macromedia Flash and Firefox) it would be having the studs sideways inbetween the programs on taskbar.
