What can I do to speed up my site?

I’m trying to speed up my site http://yourlocalproject.com/, I have:

– w3 Total Cache enabled

– Have MaxCDN set up as my Content Delivery Network

– I have minify CSS enabled but still rate as poor (F)

See my attached image of my site run through http://gtmetrix.com. I don’t know if I’m missing something but I think it should run faster.
