Heya Jesse!
Just going to be giving my opinion here;
keep in mind that I am not a map judge.
Frankly, there is no distinct THEME to your map. When coming up with a theme I'd advise you to check over this document here:
Maps List - this shows all the accepted maps on ManaCube to date, with their themes to allow you to see if a theme is already on the server. Not only this but also make sure your map is full of detail and stands out from the others, make it unique!
In regards to the BUILD, I would recommend you create a focal point for your map, a "main build" would be perfect. Creating something that you can place your parkour within and closely surrounding would make it full of detail and life!
In regards to the PARKOUR, it is mainly floating! I would advise you to create a "main build", a focus point of your map to closely incorporate your parkour within and closely surrounding. The course fits the difficulty of an easy, so nice work on this. Another thing is that your block variation in your jumps is unvaried. I'd recommend you check this document here:
Jump Variation - this will allow you to grasp a better understanding of what I mean by jump/block variation. Just ensure that you are using variation throughout the course to keep it enjoyable!
Anyways, that is all! I hope I helped you with your map <3
Cheers!
