Help with stability and design of guitar rack

[willow hedge]

little bit of a longer post but need help with suggestions on how improve, or completely revamp this design i have in mind for a Guitar Rack.
Im completely new to anything wood related so mind any blatant flaws i might've overlooked

Here i've made a few 3D models resembling what i want the rack to look like. I plan on fitting around 4 or 5 guitars on it and i just need some feedback or recommendations on any issues with stability, type of wood, and most importantly the difficulty of actually getting the parts made. I understand that it's probably more complicated of a design than it needs to be but i was mainly going for looks to start. I'll add a neck rest for the guitar later.

If you need more information on measurements lmk.

There's nothing to keep those sides from just toppling over. You need a brace between the two ends near the top and "tall" enough to help stop the toppling force.

I was going to add this neck support for the guitars. Would this negate that?

That could do it, but the key is that the power to resist leaning sideways comes from how "tall" that piece is in the vertical direction. Yours looks on the thin side and might not do the bracing job that you need.

got it, so if i make the side pieces thicker by how much would suggest? would adding just another inch to it be enough?

You could also affix it to the wall

I'd also round over those spikes so you don't accidentally stab yourself

It's not the sides that need to be thicker, it's the brace across the back that needs to be taller. Try making it twice as tall
