Not the best layout for watercooling, I guess. Using the vertical GPU mount totally overcomplicate your project.
If the GPU was mounted directly to the motherboard, and watercooling the GPU, the whole system would look more pleasant esthetically.
Usually CPU-only watercooling projects uses AIO, where the pump usually is located on top of the CPU block, so only the tubing going from and to the CPU.
I would either go for an AIO or expand your setup watercooling the GPU.
