That's looking pretty good, there. The touch of color is nice. Your new stamps seem to do the trick for you. Keep at it, you're doing good.
You mentioned you're looking for new background tools. Try the fine, cross-hatched ones like the Tandy A-104, which I have used for many years. I don't like busy background tools because the patterns can overpower the design tooling. I've tried many different background tools and the A-104 is still my favorite. To get into tight places, I filed one smaller but it's still the same pattern. This compares some background patterns. On the left is the A-104 (and the A-104 I filed smaller).
This was done with an A-104.
