Some constructive criticism:
I don't really understand the need for all the laser-receivers since all they do is drop a cube. It doesn't add anything to the puzzle and feels unnecessary. Ohh, there is also a receiver in the turret-room that does absolutely nothing. Also note that you don't even have to kill the turrets to beat the chamber, you can just portal in behind them.
There are also elements that are never used (the jump-gel and the water). I'm not even sure why they are there since you can just portal yourself everywhere.
The puzzle is pretty dull to be honest and has some flaws. Try and work those out and get the player to solve the map the way you intended.
