I began painting in the late 70's with 15mm Heritage ACW figures. Sadly, I sold off that collection in the mid 80's, so I have no examples of my first figures. However, shortly after starting with the Heritage 15mm figures, I started purchasing some of their 25mm Fantasy stuff, which corresponded with me getting into a D&D group in High School. I do have a few of these still in my collections. While the thief is a pretty straight forward paint job, the knight must have been one of my first uses of a black wash.
And here we are today. There's not a lot of noticeable difference over the past three years. A bit more attention to highlighting I think. And for humans, I think my faces have improved.
