Nice build but some comments:
Do you have enough clearance for the front wheel @ max suspension travel? Looks tight?
Other thing is that controller will be in the spray from the ground and front wheel, i had a silicon filled controller take in water and die in that position. Good for cooling, really bad for oxidation of the connectors and function of controller itself.
I'd recommend to move controller up from the ground and wheel spray if you plan long term riding without issues
