I am fairly indifferent to stickers either way really. I think it can make a board look good with some on, but hey...its not about that. I think the stickers you've put on look ok, my one suggestion would be to get some more from companies that you also have gear from (so, not just burton) that are different colours and apply them as well, just to break up the black white red scheme that you got going on there.
If you do that, you'll get +2 rail hold, and +4 pop.
