Lovely work! Do you do a lot of costume sewing? I see you have a lot of model credits in your gallery but you don't mention who made the costumes in most of them.
I have two little suggestions that are really just nitpicky technique things about the Mary costume - 1: the spats are the perfect shape but would lay better over the shape of the shoe beneath if you lined and interfaced or at least made them out of a fabric with more body (this is a form follows function thing - spats are supposed to look and be sturdy). 2: the overall shape of the corset/bodice is great but it doesn't look like you put any boning in (or is that just one at the side seam?). Spiral steel boning in each of those accent stripes would help it lay smooth and shouldn't limit movement too much (spiral steel is flexible in all directions). If the extra structure makes it ride up or puts horizontal pull lines in the fabric, put a waist stay in too. So yeah, just a couple of subtle technique things you could think about. Other than that, this is really great!
