Hello!
I would give this map a +0.5. The build looks pretty good! As far as I know, this is an original theme.
The problem I have with this map is the parkour. It has little to no variation in the jumps, with the course being mostly normal speedrun-able jumps, with a few ice, ladders, and fences here and there. The jumps are attached and blended into the build for the most part, which is also good. Try mixing up the parkour with slabs, trap doors, iron bars, carpet+fence, doors, chests, water, and other unique blocks. You can see examples of this at /warp beta :) The course is also far too long to be a medium course, as Medium difficulty courses are usually between 40-65 jumps in length.
