ok, let's draw our attention from the flashy lascannon to the paintjob. From what i can see, you need to thin your paints down. his legs looks a bit blotchy. Unfortunately most of the mini is hidden. Post new pics from different angles and the feedback will be more constructive.
I had one of these laying around, and I thought maybe it would be interesting to put it on a model. Part of the inspiration for this was a character from one of the old Star Wars books who was basically a walking laser cannon. Thanks for the comments, good or bad.
