thx :) and not to simply skip the page, I leave you a comment.
First, I think that the gameplay aspect of the map is very good and fun. So if that was your only goal, you have the choice to stop reading here ;)
On the aesthetic side:
I have found some strange lights.

And the big one ;)
The contour of the illuminated ground is also a bit strange in the underground passage. And I think, the contrast is not ideal.
These blocks are too much into each other.
Another texture or stairs in place of the ramp would look better I think.
And one last point, I have some troubles with the sand deposits. How did they get there? why are they so large and that convex? trickjumps, I know…:)
However, maybe more concave and better spread (the wind or something)

That one looks a bit nicer

Otherwise it's agreeable, with the torches :)
