This map has a lot to offer in terms of puzzle solving. With so much detail, it's understandable that there are some alternate ways of doing several parts. But don't be in a hurry to fix them - those options make the map more interesting and enjoyable to play (or replay), especially when the choice is between a hard solution and another hard solution.

I'll just suggest a couple of things, if you ever do an update.Suggestions
[spoiler]There is a little room between two glass doors in the middle area, with the "square" icon on the ceiling. You can shoot a portal onto the wall of that room from the lower part of the middle area, which allows a couple of skips. Can the portalable wall be put on the opposite side of the room and still leave enough space for some grating to shoot through?

To prevent an easy skip of the last part, make the laser catcher that opens the exit elevator doors so that it can not be activated by a laser vertically from below.[/spoiler]
Now I need to find some other maps like this one.
