Hi super
Overall, its an ok map. The parkour is good, its nicely varied, and fits the difficulty, although it does feel too easy. Maybe make one or two slightly more challenging jumps.
The build is simple in terms of detail, although I would give that a pass for this theme. The biggest issue though, is that it feels like the character was flattened. I recommend making the build more round, and adding more texture to the body to get more detail. Maybe you could have his arms pointing up and down to make it look branches of a real cactus like this:
