The gaps between the tracks is interesting. I'm guessing you did that intentionally, and wondering why. Not that it is a bad thing - it's just different from what I mostly see. If you run non-magnet cars though, you may find that cars deslot when they slide around the turn and the rear wheels fall into the gap.
Here is a thought that I have been considering for my track (or my next track) and one you might be interested in. Since you are 15, and mentioned that part of the track build will be for a school project, and if you learning geometry, then you might impress your math teacher as a bonus.
The idea is to give the perception that the cars are taking the 'inside line' when they go around corners. Look at the track slots on the following pic:

- thanks Crimnick!)
I'm wondering if we can get the same perception across by painting borders around the track, and not painting the track itself.
Four lanes of track is 6" wide. If you make a 'virtual' track that is 9" wide, and then vary the extra 3" on the inside and outside, you can accomplish this.
I did a scale version (ala Sed6) of one of my track turns to test this idea.
Here is the actual turn:
Here is a one third scale version on paper:
And here is the same scale turn, except made with a virtual track that is 3" wider.
Painting red/white stripes on the inside corner like Cordoba has done here also helps the concept.
If I would have adjusted the straights entering and exiting the turn it would have looked better. In addition, if I would have altered the virtual 'apex' of the corner in relation to the fixed plastic track corner apex, it would sell the idea better. The geometry came into play as I calculated the radius of the circles.
Just a thought....might be more work then you (or I for that matter) want to do, but I think it could be interesting.
