Hey Twistkin, here is my critique of the map.
Unfortunately, the theme you chose is unoriginal as we already have a donator map called Cyclone. The build is accurate to your theme, but it could have been executed better. Try mixing in other blocks and adding shading to your builds! For the parkour side, your entire map is all floating jumps! This is a big no-no in the map making community. The majority of your parkour shouldn't be floating and it should be on the central build. For jump variation, this map is very unvaried. There are strings of head hitters and neos throughout the map. This is also a big no-no when it comes to map making! Typically, you want your parkour to be unique and feel fresh to play. You can mix in other blocks for jumps such as flower pots, piston heads, heads, beds, enchanting tables, doors, trapdoors, brewing stands, soul sand, fences, cacti. The parkour doesn't match expert difficulty as it is very easy if you are decent at parkour. A majority of your map is z-facing single neos, 3+1s, and four block jumps.
Good luck!
