Thanks mate, to be honest I think the watercolours used at the time were just out of a standard set, nothing special. When I'm using watercolours though I try to use decent watercolour paper as its quite sturdy and holds wet areas very well without warping or distorting. That can make a difference.
I dunno why but I've always loved images of urban warfare - this is no exception Great work. I think that perhaps the guy on the left may have a slightly too large head but given the camera angle I wouldn't be too sure about my judgement
