Very clean wiring job, looks great! I also would consider rotating the esc 180 deg. also, not only to shorten the lead wires, but also to make sure your body fits. Bodies like the Parma Speed 8 and the Protoform Speed 12 can be slammed very low. On my car there is literally no clearance between the top of the batteries and the body. This means the wires need to be lower than the batteries & esc as not to interfere!
Other than that, looks awesome! Good Job!
