Fairy Council: reasonable, you can get a little more than 42000 in this level
CF: okay, you can get 105000 in this level
TBOM: bad, as you admitted yourself, but I don't blame you for that score; getting the hang of all combos in this level is incredibly complicated. You can get around 100000 in this level (with the triple glitch in part 5 100800, and with the double glitch 99999 (though you'll never get that))
LOTLD: there's room for improvement in this level. You can get 105800 using the combo in the skating tunnel, but 119599 is possible with the combo in the doctor's office.
DOTK: reasonable, it can be improved to 109749 though.
TLS: good enough, you can get 41500 in this level but it's difficult to get. Improve this to 41000 and you're done. This level is too easy for words.
SBTC: not very good, you can get lots of better combos in part 1 and 2, and in part 3 you have to make as good combos as possible using the kickflips. Also, restart this part until you combo the green gem, it will be more than 6000 extra points.
HH: good, this level is pretty difficult and you're going to have a tough time improving your score here. The highest score possible is 109009.
TOTL: bad. You harshly need to improve your score in this level. The maximum score is 104499 using the Xowar chamber. In the first part you can get more than 55000 points. Tip: Get a Lockjaw right in the beginning by jumping on a ledge.
That should give all the info necessary for scoring in R3.
