I like Simphony and Simmetry Design.
As far as Pixel Simmetry goes, even if the other site is spelled "symmetry," you're going to get people that don't know how to spell it either way either going to their site, or coming to ours, and being very confused.
I don't really like Sims-Pixels-Art for the same reasons: It doesn't roll off the tongue (your mind?) easily, and it seems like it's a list. A site should have an easy to remember name, should sound and feel concise, and shouldn't have an insanely high probability of being misspelled.
The reason for the lesser ability to be misspelled, and the more concise name, is so that if someone wants to search it, they get us, and not some random other design page?
