Well some parts need work like the huge blurred area. I can see what you're trying to do with making the focal stand out more but it just makes it fugly. I've seen that render before so I can tell what you're working with and it seems that you did pretty good to make it fit.
Not your best man. Blurred foregrounds only work if the foreground is consistant (so that you cannot identify what is in the foreground). Plus The pink wireframe looks ugly, and I think a darkish background would help.
