Me and my friends are building a track

Track layout in the image. We have 6 1/16 losi mini B’s. Brushed. What do you think about this layout? The blue section was added after the fact. Yellow are cones. Blue is chicane and green are small jumps. What can we change? Where do you see pitfalls?

And also if anyone has any general advice as the track is on a low populated car parking but still has to be dismantled after each use, what materials/solutions did you find helpful?

Ty all!
