Oh, that practice thing. :-D

Looking good. If possible (if the grid texture actually represents the actual polygons) you may want to eliminate more of the triangle polygons if the clothing will actually be folding. Triangles fold unpredictably whereas square/quad polys are a little easier to control. 

There are some excellent ways to make dynamic cloth using triangular polygons based on quads but for bending linked to skeletons, quads work better.
