I'll probably be doing some more fine-tuning to these, but I thought I'd stick 'em up as they are at the moment, for an 'under-the-hood' glimpse into the 'artistic process'* The green one needs another darker outer layer, the brown one needs more dark colours in the centre area, and they all need around 25% more detail work (outlines, inlays, smaller dots and circles) I'll know when they're finished 'cos they'll start to 'zing'...
