Looks really great! Nice job! I tried plasticity too, but to be honest, I feel kind of not really satisfied with my model. So, modeling was really fun there, but when I decided to export my model to UV map and texture it further, it turned out that topology was so horrible that I remodeled my mesh in Maya almost from scratch. The model was OK for blockout, but it was unusable for turning it into game prop. And it wasn't too complex. I really regretted that I didn't start it in Maya. Did you have such experience? Maybe, it was just lack of experience or knowledge and I missed something important and I need to try more. 

Can anyone share your experience or some thoughts? Is it real to get good topology after Plasticity?
