This sounds like a fun mod, will watch it and hope it will be released when you're satisfied.
As for suggestions, i think it would be best for you to release a beta before adding too much stuff, the more you add the bigger the chance will be you will encounter problems. Same counts for the beta testers. But thats just my opinion since you already added 25 quests.
Im quite curious how this will work with FCOM myself. Also, have you altered parts of Cyrodill or did you create a new landscape?
This will be important for compatibility with other mods (not something which cant be worked around though

)
