Very good attention to detail, adding lasers and such - but needs a little refining. The whole scene looks a little cramped, try spacing it out more.
The beams and lasers aren't
that bad, they just need a little work - are you using Photoshop for the render? If so, and if you kept the beams etc. on seperate layers, make liberal use of the blur tool and you would have one sweet render there

But, I've just noticed, the lasers have little circles at each end... Not really Photoshop, I don't think... Anyway, check out Thunder's website for a good beam tutorial

I don't like criticising things other people have worked hard on, and I hope it came across as constructive

Good work.
