Only been painting for a few months, thought I'd post what I've got so far... If anyone has some constructive criticism feel free to lay it on me.
Second upload; after some advice I cropped the image, but it lost the original URL
The highlighting is very nice. There are a couple of areas that have small paint splotches that should be cleaned up. The hand holding the gun could also use some work as well as the gun itself. You should also thin down the metals and probably give the armor joins a black wash for more depth.
