Great work Peter! I love the motley look of the marching pikemen and also how you've mimicked the puff and slash of the later period doublets and hose. I also like your idea of using a deeper base. I do this with my Napoleonics as the extra depth allows for the odd out-of-step figure/casualty/officer and any indulgences in groundwork.
Hmm, I've yet to crack open any of the boxes I picked up for this project but after seeing yours I'm feeling a distinct urge to give them a whirl.
