My custom Watchmen shoes. Also, suggestions! [somewhat NVGR]

Ok, so I've taken up the art of custom shoes. I've been making custom shirts for a long time and had this idea for shoes for a while, too. After seeing the Zelda-themed KyozoKicks on the front page the other day, I decided it was time to make my idea a reality! So I went out and bought the paint and shoes I needed, and went on my way. Here is the end result:



My expert photoshopping skills are also present!

I went for something rather simple, but yet strong enough to convey the reference. I included the panel just in case for those unacquainted or who just forgot.

I created them the same exact way I make shirts, I trace the design onto freezer paper, which I then iron on top of the shoe. Once it's in place, I iron on any "islands" that need to be there (for example, the middle of the O or B), then take a roller and simply paint over. Once it's dry enough, I simply remove all the freezer paper and viola! Custom shoes. Once I plan for more intricate designs, the roller isn't going to cut it and paintbrushes will need to be used.

So, what should I do next? I've already got some ideas in my head, but I'd also like to hear of anything you guys might think of. I plan on doing mostly slip-ons, but I definitely also want to do a pair of Converse, just like KyozoKicks did (amazingly!) here.

So leave feedback on how you like these and any future ideas you might have!!!
