Welcome to the forums
Do you have any specific questions, or are you just looking for general input?
Have you chosen fans for the radiators?
What case is this going in?
One big thing that sticks out immediately is the Mayhems Aurora coolant. I know it looks amazing, but this coolant is designed for show purposes only, and isn't intended to be used in systems for more than a couple of weeks because it will just start clogging up the blocks and fittings. You should definitely change your choice here; something like Mayhems X1 is perfect for long term use.
Do you plan on expanding the loop at any point in the future? A graphics card or two for example? If so, you'll want a better pump so that you have the headroom to expand the loop in the future without having to buy a new pump. If you're just keeping it as a CPU loop, the pump will be fine.
Nice looking fittings by the way

Once the loop is setup it will be worthwhile learning how to overclock the CPU, TTL has a great guide on it on YT, and you'll be able to get a lot more out of your CPU without temperature being a problem.
