Nice! I customised my dock to an iOS 7 inspired theme, I think the uniform icon shape looks so much better than the original.
Can you give us a link to this dock or where you got your images?
from where i can download DockMod themes?
I have found some nice ones on DeviantArt...just search Dockmod and you should find some results.
I'm sure there are other places as well, I just don't know of them.
