Well, aside from doubling up what others have already said, maybe use the scaling on the upper (what seems to be snow drifts) on either side; the ledges. Right now the overhang out of the level of it seems a bit choppy.
And remember, though speed will have people playing faster, it is better to simply do things as well and perfect as you can with your own abilities. If you have trouble, don't worry about asking someone else. This is a fairly good map (even more so being an update to your first), and only problems I have found are those mentioned above (plus my own).
