It's decent with a 5-sec look. Longer and you'll ask why the hell the EBC solenoid is so far from the turbo, why the temp probe is on the coolant out instead of next to the ECU sensor, what the hell they're doing with the catch can / breather setup, why they're running an S14 radiator in there with zip-ties, what they plan to do when it rains, and why their standalone needs an EBC to begin with!

Overall, good first attempt. A real clean bay requires more planning, more knowledge, a keen eye, and more fabrication.
