Hi! i will give you some tips for your next maps, as this one, is lacking some essential stuff when creating a new masterpiece.
First of all, the building looks pretty sick, for someone's 1st creation it looks pretty decent, but as
@Uduntreal said, arent map judges favourites,
If you want to get a great theme, try searching if your map meets the parameters for an accepted one
here.
Now, the parkour is a big issue, as the only source of parkour you used was normal blocks and 1 ladder (from what i remember).
For building parkour, try using variation, playing with objects hitboxes and tiers (solar panels, cobble walls, beds, flower pots, piston heads, etc), as it makes the parkour more enjoyable.
Otherwise i think your further projects have potential, good luck!
