Swaty, to be perfectly, PERFECTLY honest, those changes look to be almost entirely cosmetic.
While lowering the two side areas will add interest and change the gameplay of that CP some, the issue isn't the lack of height in that area so much as the lack of access. There's a big, big, wide open area, either way. You didn't add any new geometry, really, except that wooden plank ramp up to the concrete/grate main path. Otherwise, the changes are really the visual changes of the planks.
Your focus should be to differentiate the sides so that each has a specific advantage and disadvantage approaching the CP. You could improve that area moving the CP closer to the entrances or by even adding some kind of structure in the middle or to the side of the area. Some sort of new, playable, geometry.
No matter how you look at it, it's still Granary's last without the pipe, right now. I'm especially worried that it would be hard to push out of that area with only two exits (left & right) since you have no third route (for pushing out) like the pipe on Granary.
Although, the one thing I think you did improve there is the sightlines, since you now cannot see from one side to the other. The only thing is that I think you need to work on sightlines from last to 2nd rather than side to side.
Also, in the second to last screen, it looks like accessing the point from that left lower area would be tricky and require walking past the enemy's spawn (and that ridiculous rock).
