DIY Pressure Washer shelf unit/wall unit.

About to attempt to build my own wall unit for the garage.
Look over this and critique it :-)

What would you add?

It may not make sense.

I have an area of wall that has plenty of height but about 21.5 inches of free space in width between garage door frame and master blaster with 20 amp breaker picture #4. I've already relocated the hose to the other side.

Planning to add a plywood backing wall 5 ft tall by 21.5" to support the shelves and have the ability to add more stuff to it it later. It will he very securely mounted to the studs etc yo support the weight of 45 pound pressure washer hose reel. Heavy hose etc. Plan to sand it all and stain it gray when done.

Anyway.
Simple shelf for pressure washer with triangle braces.
Reel wall mounted below.

The question is the 2nd lower shelf. I plan to make a separate duplicate shelf below.
Two notches in from each end like the clamp rack shown to hang 2 foam cannons.
A row of 2 of holes drilled out to hold all of my extra pressure washing tips.
Maybe a slot/shelf for pressure washing guns?
Maybe a spot for my angled pressure washer wand?

Thanks for your time and any feedback.
