One, I really tried out a new method. I was for the longest time sold on my past method of painting, the total leveling up of the paint, etc. However when deciding to get back into painting, I looked at some other's painting methods and studied them. I've already got a solid foundation, but now I wanted to expand my knowledge and potential as a miniature painter.
Pretty much it boiled down to the quality of paint and in what form of suspension, and PATIENCE.
Anyone who knows me, and how fast I used to paint, knows I have little patience. However, now adding in the ability to shade with glazes/washes in a controlled manner will actually INCREASE my painting time, and on some minis will make it turn out better looking. I'm not completely sold on my new method as it doesn't work with all colors/paint types, but I'm getting there.
As with anything you do: with understand comes acceptance, and with acceptance, comes action.
I just had to want to understand it and apply it until I figured it out myself.
