Hi ChiknStu!
I am here to tell you my opinion of your map. Please remember that I am not a Map Judge and my opinion does not affect the result. If the Map Judges disagree with my opinion they will decide what they will.
Firstly the THEME of your map. This theme is NOT original unfortunately original as there is the map Steampunk in insane (there may be more that I do not know of). However, since there is only one, and this map is fairly different from that one, I think this should be fine.
Secondly the BUILD of your map. Although I do love the build, having much of the parkour in the air throughout the map does take away a little from it. However, I know with a steampunk theme it would be very hard to lessen the amount of jumps unattached from the build. All in all though, nice job.
Lastly the PARKOUR of your map. To me, this is the biggest downfall of your map. It wasn't varied well at all. In the future, be sure to include more blocks such as heads, enchantment tables, anvils, water, stairs, pots, soul sand, brewing stands, slime, trapdoors etc. I also found the map to be a little too easy for expert, more fitting a fairly difficult hard map. I did find the map to be fun throughout though!
I'm giving the map a 0 for now, because the theme is ok and the build is good, but the parkour is lacking.
Good luck, JJ
