Ok - just did a quick tour and my immedicate thoughts = well done big improvements
He are a couple of things I found:
1] the rock by the cliff has a gap between it and the fence = definite sniper advantage for red fix it or put in a block bullets to take it away.
2] Love the mouse hole out side of red's 1st spawn - you should put the flanking tunnel near there from that door near red valley sign 2nd floor
3] The new balcony = great, maybe leave that door open (for spies to attack from behind) or if not you have to fix the missing texture on the inside
4] I love that new little drop down you put in near the final cap
5] for that new balcony at the last cap - extend it out to the railing to make it a little wider and angle the end so it matches the shap of the existing building.
Think about the cap point thing but other that that well done
Edit:
1 - the balcony modification needs more work under it - a small detail yes - but just looks a little odd in current state
2 - 1st cap point the bridge with the 1st aid bottle - rotate the wood planks 180 degrees
