Hard reject now accepted, so how do I market it?

http://graphicriver.net/item/cool-robot-mascot-with-custom-features/13215602
After numerous rejections, with thevsame two items. Finally got my first accepted item. Feel excited. After really trawling through the guides. And changing my item I finally got it accepted. After this one (the better of the two) was rejected. I went back to the drawing board, added alot more custom colours, added a head only psd, a version holding a sign, added an in depth instruction word document, added Pngs and finally put it in the right category ha.

So do you guys have any helpful tips on best approach go market your items?
