I think that's a pretty cool build! Definitely looks a bit strange but you've done a nice job incorporating the Galaxy cage onto the Viper chassis.
EDIT: If this is going to be a runner, I would recommend modifying how you mount the wing. Mounting it the "stock Galaxy way"--by screwing it right onto the plastic rollcage stand-offs with self-tapping screws--is probably going to cause it to rip right off the first few roll-overs. This could damage the stand-off threads and strip them out and will definitely damage the wing.
You might consider a mod like what I did with my Galaxy. I installed standard wing mount buttons in my wing and bent a wire into a squared-off U-shape, then drilled straight through the stand-offs. I then inserted the U-wire from underneath, attached to the wing buttons, and used zip-ties to keep the wire firmly in place. Should be more durable and also allows you to adjust the wing by bending the wires to your taste.
