Finishing a WordPress Theme, feedback needed

Hello ! I am currently at the last stages of developing a WordPress Theme for bloggers. It still has some issues, but it’s nothing significant. In my opinion it looks pretty clear and there are chanses to be accepted. The only thing that bothers me is that it looks similar to some recent uploaded items… but i was developing it for the last 7 months :slight_smile: (part time project)
Here’s the DEMO
Don’t pay attention for the current load time, it’s because images are unoptimized, no chache instaleld, and unminified scripts (dev version, because debugging on server)
So, what do you think ? What improvements would you recommend ?
p.s. How do you think, will it look better without individual category colors ? (just one color for all categories)
