How to improve my blog's appearance?

[Snoozy Suzie]

I started a blog in late november/december time, and I really love it, I enjoy posting, I like editing the design, but i just don't know how to make it look more sophisticated and professional, Have a look: http://lushfreak.blogspot.co.uk/ and tell me what you think, I am in the process of removing the '.blogspot' from the url. I also just made a facebook and twitter account and I'm in need of some more followers!
