Oh come on, the yellow lines around the tori looks very fuzzy, make it smoother please, it looks so awful.
The background choice is also bad, well Idk, did you just using a bare silver background and added something that you found on google? they're not even close, not suitted, and looks kind of bad.
Watch some tutorial on making gfx (just for example) with cs6 in youtube, it'll improve your knowledge about cs6 a lot more, I learned my gfx making from youtube aswell. So, it's going to work if you focus on watching the video/tutorial.
