hey eZTarg, after looking at your painting i think you have two big problems.
the first is your values, there is no mood, no atmosphere.
Second is the rendering, i only see hard edges everywhere.
Try this, take one of the awesome warhammer 40K illustrations by Adrian Smith and turn it to black and white, then turn your own work to BW too, compare the values.
For the rendering, study, watch videoturials, etc...
There are other minor problems too, but for now, i suggest you to focus on this two.

Just a quick question...do the values and saturation on this look kind of washed out to you?
