I like the blue
But the metal looks a bit dull..
I think you should paint the metal areas black before you paint on the metal colors or just undercoat the whole modell black..
I've gotta say, that's one goofy looking sculpt - it has the proportions of a Loony Tunes strong man! Clean paint job, but the white areas could do with some shading or detail, especially given their size. (Maybe a Warner Brothers logo?) :-)
