The cuts look nice and clean. (No burn marks)
What type of bit did you use?
Do you also control the router RPM?
I'm starting in the sign business and thought I would show some of my work. This sign is a single 1 inch maple board 14" tall x 24" wide. I made two signs and put them back to back to make it two-sided. It is my first sign and it hangs out at the end of the driveway on a nice signpost.

I used a 1/4" carbide endmill and ballnose upcut bits for the trees and profile cuts. The lettering is done with a carbide tipped v bit. I have found the maple works best at around 60ipm 8-12k rpm(Porter cable 1 3/4HP controlled with super PID controller). 1/4" passes and I tweaked the feed speed a little on each different part. I have found that V carving can be run 30-40% faster than other cutting.
