Took a look... you did fantastic! Now it's time to start playing with unique shapes, sizes and patterns.
I wish I had a photo of the "Iron Cross" stippling a friend of mine did. He ground and filed a square iron tip to an iron cross shape and impressed that shape in deeply, in a kind of sunburst pattern from the center of the grip out.
Here's a few I found on line that are interesting.
Cheers,
