Just to be clear. I'm not suggesting for one second that you plaster the whole model in pointless greebles and paint it all the colours of the rainbow. There's nothing wrong with it being dark grey and largely featureless. The mesh you have is great and it's a nice design (as I've mentioned before) it's just too simplistic to get in close to. It needs more going on to not only add interest, but to also add scale.
