Nice job!! Painting 54mm is not as easy as one might think, is it? It's assumed by some folk that, as everything is much bigger, it's easier, but I don't find that to be the case. I've just started a project in the same scale, using a 'dip and highlight' technique and it's fun, but I am finding that I need 2 highlights on pretty much everything to get the effect I want.
Anyway, keep up the good work. Good to see the 'big toys' getting a look in...
