Ok You asked for comments and as this is your first mini ther are a couple of things that you might want to consider. You'll get better results by painting the metallic areas first . That way you can tidy up around them and paint the chromatic colours up to the edges without having to worry about the metals going over the areas you've already done. You already seem to thin your paints to a working dilution which is a good start and I think that you'll find adding a careful wash of shadow colours into the recesses of the clothing a benefit. It will take control, practise and patience but it will be worth it. Good luck and post some more painting.
