Your really giving this a good shot
I think my first question would be , what kind of brushes are you using?
Painting minis, your brush is probably the most importent thing that can either help or hinder your work.
I use pure sable kolinskys because they keep a point and hold a lot of
paint at the same time.
They are not ment for work in acrylics though. Just oils or water colors and gouche
I'm pretty sure you know all this but I thought I would toss it in anyway
I'm glad you are continueing to do them.
