The house, the cap and the table at jump 9 are floating.
jump 8 was still a bit dark in my opinion. And this unjumpable wall could maybe get another texture, cus right now every brush with this texture was jumpable excpet for this one.
You can get up here at jump 7. It isnt really a big jump exploit gamebreaking thing, but i feel like it would be better if it would be raised up to the wall. Furthermore i dont really know what jump 7 should be, i guess its a speedshot but you can just jump it as well.
At jump 6/5 the walls arent connected to the ground (so they're floating). The props on the ground look weird to me as well, like a truck standing on its nose and a cart on one of its pipes, kinda weird.
I actually couldnt see this texture while playing but while in spectator i saw it, sooo: use some nodraw
heres a good explanation

which explains nodraw at the end but i can recommend watching the rest as well
Here, the part just after the long wallclimb, you have some brushes not connecting to eachother. Ive seen it somewhere else on the map as well but couldnt find it.
This area, right after the long wallclimb, is really dark. But because it isnt really in the gameplay space, you could better just make it a wall imo.
