I'm not normally a connoisseur of tech tracks, but for the new guy, I decided... oh, what the hey.
First of all, I have to say, your track designs generally flow together really well!
My only complaint is that the checkpoints are often poorly placed - A running theme in most of the tracks that really ruined it for me.
There were also a few instances of me getting lost or jumping off the wrong ramps, but that's nothing that a few well-placed signs can't fix.
All-In-All, I expect some great tech tracks from you in the future... just remember to double-check the checkpoints and you'll be in the clear.
