Sadly, your map has been denied!
Reasons for this include:
The map does not feel like a parkour map. It feels like you made a pixel art and just slapped some tough jumps onto the art. We get tons of Pixel Art Parkour submissions, and thus we need to see the best of the best from pixel art, and this did not stand out.
On the plus side:
You have a good sense of difficult parkour, although it felt more expert than insane, despite the amount of jumps.
The Pixel art itself (Without the parkour), looks really nice.
Remember, you can always submit more maps at a later date,
