First off, let me thank you very much for posting a NoLimits track. We don't get enough of these.
Now, onto the constructive criticism.
Your trackwork (as stated above) was good and bad. Bad in the sense that there were really a ton of pumps. Bad ones too. Also, the zero-g roll was... Oddly executed. Good in the sense that the g's stayed in check almost the entire ride. The only bad parts were during the inclined loop, there was a spike in laterals, and there were a few high lateral g spikes.
The supports were okay, but you should have used a thicker tube type, those thin tubes didn't look very stable.
Overall it wasn't a bad first track, just a little quirkey in some senses.
Also, I would recommend learning Newton2. I think it would be great for you to learn it nice and early, unlike me and many of our fellow NoLimiters.
