I think it looks good. I agree with the previous suggestion of using solid colors, it will be a lot easier for printing purposes. I would make the ring solid black, and then either use white and green, or two different greens for the other colors. For your particular logo I have a few suggestions that you may want to implement to improve upon what you already have.

I would take that black line around the "R" and make it substantially thicker. This will make the "R" stand out more while still keeping your same design. Alternatively you could just make the outer ring solid black and also make the "R" solid black. The purpose for both of those changes is so that when you're standing across the room or field or pits and you see the logo, it's easily readable and recognizable.
