Nice Job!
I am not an OSB fan but they look good.
My suggestion would be to use at least a 1" hi density foam in the corners to provide impact resistance.
It is relatively inexpensive & you really only need to put i in the corners.
Hot glue works the best to stick it to the walls.
That way if it is dropped or banged around the impact would be minimal.

I'm not to up on my engineered wood products but I think what you are using is 'Particleboard' rather than 'Oriented Strand Board' (OSB)

OSB is stronger than plywood and uses a similar adhesive.

I'm shooting from the hip here but anytime you see big pieces of what looks like chips of wood, it's particleboard. At a glance, OSB looks more like sawdust but if you look closely, you can see that the wood is slivered and all in the same direction like a wood grain. It's then layered like plywood to give it it's bidirectional strength. I haven't looked at engineered wood in years so I could be wrong. I know that engineered wood joists are becoming popular in residental construction though and I would take that as a good sign.

I agree with Marcel. I don't think there's a standard for what you have, but they look like a functional and cost effective design.
