SM7E: The Second Round (new multicup)

I'm planning to make a sequel to my multicup Mario Kart PC: SuperMega7 Edition. It will be exclusively be in Complete mode (so there is no QM version of this, unlike the first one).

The number of nitro and retro cups will be the same as the first one. There will also be a battle mode.

Finally, there will be new original characters! In consequence, there won't be any default characters in this multicup...

Here are the tracks for now:

Note: the cup and track names are placeholder and are not final.

I will allow you guys to request any track of mine you want to see return! (I'm not sure what I'll do with the MKPC: SM7E tracks, maybe I'll remake them again for this multicup)

Edit: just wanted to specify that you can only choose tracks from MKPC: SM7E and my QM SM7K trilogy for retro tracks... Sorry if I wasn't obvious enough...

Edit 2: you can also request a name for the nitro tracks and cups, since they're obviously placeholders.

I want to see the two top rated tracks you've made
Specifically, tracks. Not a cup or multi cups, tracks.

I'll Request A Track For This!

My Request To See Return Here Is Waluigi's Bumper Land From SM7K2: BFAB!
(I Know It May Be Weird Requesting This Track But I Just Think It Could Be Nice Seeing It In CM..)
(Rn I'm Requesting This One Because Idk What's The Max Amount Of Tracks To Request But Yeah I'm Requesting Waluigi)

I guess the maximum of retro tracks you can request is three (each must be from a different multicup)

I would like Tree City from MKPC: SM7E to return
