I'm assuming that's from Bill & Ted's Excellent Adventure. That's a movie that you don't see quoted too often!
Here is a minor update. I found out that I had some pretty decent symbols in my CC2, so I made a sheet with them, saved them as a JPG, then erased the background, and simply cropped and then dragged them to my map. There is probably and easier way to do it(any suggestions would be awesome), but that worked. The only downside is that each symbol was a new layer, so I grouped them into folders by each type.
Anyway, let me know if this looks a little better.
