Please remove the fence in blue.

No splash on this thing (as well as poor clipping on the ends) will be hated as much as the planks on badlands mid (probably more)

When people have to move through a small area you need to have a smoother elevation change. As it is it will sometimes make players stuck and will always stop splash damage.

Please redo spire. Please make it more like process spire. Recycling such an iconic model is bad, and process really has shown that more subtle spires are more class balanced. I've draw a new spire here. It forces the space behind the spire to be more of a focus because it is accessible.

Adding this new spire would also remove this annoying spot.

These areas really need to have a little bigger doors (and maybe have some of the props removed) as players will now be moving through them with greater frequency.

You should also cut off the end of the railing at the end of the stairs. It is shown in purple.

You should also compile the map under different settings to remove the lighting bugs.
Looking pretty good so far. :)
