Well, my first impression is that it\'s dark. There isn\'t enough contrast in the detail to make it interesting. It looks as if you put some time into the details, but they don\'t stand out. That could be the fault of the picture, since I can\'t see the figure close up in better lighting.
I note you said you painted it to be \"dark and brooding\", which is fine, but it doesn\'t tend to get attention from folks who like to look at exciting paint jobs.
My challenge for you then, is to find a way to paint \"dark\" without using black. Make the figures look mean, scary, and evil with other colors.
Take a look at some of the stuff here that is getting high marks and note the color schemes and use of highlighting.
