you need to find the BN's yourself, pending category doesn't actually do anything, could even just post everything to pending and ignore WIP section if you wanted.
go
https://bn.mappersguild.com/ for list of all BN's and whether they are open to requests or not. go to their profiles to see how they wish to be contacted.
probably best to get some mods on the set first though, just read the rules in the pinned threads first
community/forums/60Edit: just took a look at your map, seems you're still quite new to mapping, your first few maps will probably not get ranked and you're best off focusing on improvement for a while instead of spending effort trying to get BN's attention.
For right now I will say you should delete all the red lines but the first one and remap only using 1/4 beatsnap divisor, most of the objects arent snapped to any sound in the song, focus on getting the rhythms right for now.
I see youre using the red lines to get slower sliders, dont do that, use green lines by checking this box and lowering the multiplier
