Hey there, my personal recommendation is in the [Plot] question in the map submissions format I would suggest that you add a direct teleport command to your plot, for example, this is the location of your plot (/plot v alxecepher 1) It's much easier for Map Judges to head over to your map submission and review it. For an easy/medium map you've got a fair amount of parkour jumps and from my perspective, that amount for this difficulty is quite satisfactory, (no pun intended). Personally, before going further into detail I believe that you could make a more creative name for your submission instead of just 'factory' sadly there already is a factory map in parkour so your map isn't quite original.
Details ~ This part is one of the most essentials parts of map submissions other than the parkour, sadly your factory doesn't seem to have much detail at all and just seems like a world edited box made out of stone bricks and some small cobblestone towers on the roof. I'm not here just to criticize you and honestly, I believe that with enough dedication to the task you could really spruce up your build with more block variety, for example possibly grey concrete, cracked bricks, windows, different colored/mixed smoke, etc.
Block variety ~ Personally, in my opinion, your parkour jumps are quite basic and need more detail/block variety to keep your submission interesting. For example adding soul sand jumps, enchantment tables, slabs, ladder jumps, head hitters, slime jumps, etc to really add that bit of color and detail to your build!
You've got a little ways to go but I believe that with determination you can make it there, good luck! :)
