This is not bad, definitely tabletop, although the pic could be better. Work on your highlighting/shading of the metalics and your score will go up. I agree it might be too much metalic for this mini.
I think you need to lay off the matalics big time, i find matalics are best used in small amounts. Also i think you need to use more 'normal' colours, like reds and whites. But its a good start.
