What defines a map is its theme. People won't remember a parkour map if it is a sequence of floating blocks, now will they? I suggest before you make another one that you really think what sort of map you want to make. Do you want to build an object, a city, one inspired from a video game you played the other day? I'm sure you could think of a hundred different themes before the clock strikes midnight!
So whilst I urge you to continue your endeavors and progress, this map is an empty shell at best. The parkour is unoriginal but perhaps you can learn from this experience. Go play some of the [Accepted] maps, or venture on Mapper's plots to draw inspiration from their jumps. Then instead of an accumulation of floating jumps you could have more ladder jumps, or fence jumps, or carpet jumps, or stair jumps! Your intentions are good and you're breathing life into the [Map Submissions] sub-forum, so that's what matters most!
