Thanks for the feedback Mads3 and Presidenten, but I do feel like I added a lot of detail and inside the giftshop is very detailed but i guess the giftshop building itself is a bit plain, I tried my best though. :D
It pains me to have to tell you that your map has been REJECTED.
Theme: I'm going to have to congratulate you on picking out a new and fresh theme that we haven't seen done before. There are no maps that are themed after a "Gift Shop", well done!
Build: The build is the main reason I rejected your map. I just don't think it was executed very well and I'll try to explain it to you as best as I can. First off, the landscape is bland and cluttered. The whole map just feels tight and cramped up. Although I noticed you tried to be very detailed, it wasn't executed properly. The gift shop itself is just a rectangle with messy parkour all around it and an interior that is very underwhelming. This leads to my point of dimensionality: the store has no "depth" to it (as Pres mentioned above). It's definitely a shop, but, just not a good one. And, the outside elements could definitely be worked on.
Parkour: The PK length and difficulty definitely fit the medium difficulty, good job! I also found the parkour to be enjoyably varied although you did use a couple of blocks one too many times (for example, enchantment tables) but it wasn't a major issue.
I hope you take these criticisms into consideration when submitting maps in the future, good luck!
