Thanks for offering your levels! 
I planned to take a look at your levels anyway after I finished the next update to the intro pack.
So here is what I will do: After I played through your levels I will give you some feedback and then after some possible fixes I will throw the best onto the community pack level pile.
Just be a little patient here as I still need to work on a few things in the intro pack.

In terms of music: I will not promise anything here, as that will be up for debate when everything comes finally together. Also, I will see that we don't have like 80 music tracks in here. But, I can keep the track in mind for the final track list.
In terms of the state of the community pack as it got a bit quiet in here: This is not abandoned, but we need to gather some levels first before we can make any more detailed plans. I noticed that I need to update the list here as there have been some resubmissions I haven't updated here yet. Will do that over the weekend.
I have gathered around 65 levels so far, most of them were resubmissions.
Future planned steps after I finished the majority of the work on the intro pack:- Excavate the last few contests and ask around if I can include some of the winners/runner ups there.
- Take a look at the levels we have right now and evaluate if they are indeed well made. Most of them should be anyway as they were contest entries if not winners/runner ups. But there are a few pretty unkown to me and I at least want to know what I am including here.

I won't be very strict, but let's say they should be at least of decent quality.
If I get close to around 100 levels we can start and sort the levels very ROUGHLY into difficulty groups and see which type of levels we still lack (+ also discuss the final pack and rank size). Then we can specifically fill in those lacking areas.
