Hey ChrisATX,
I'm going to give your map a +1
The theme isn't original since Katrina already mentioned there are lots of Mario maps. The build is really good and well done, as well as being accurate from what you were trying to base it off of.
The parkour is good, you added the parkour into the build very well, as there were little to no floating jumps, so in that aspect, you did that really well. The parkour is pretty varied, I would suggest maybe in the future looking into using more unique blocks in your jumps, but that wasn't a huge problem and was still done very well. I also thing it is well suited to the easy difficulty.
Good luck! :)
