Culture Clash Fanfic: Would like critique please

Hi everyone, it is me...The creator of the Space Beasts Known as Twiga on Writing.Com and Rebel Mutant on Fanfiction.Net, I made a story where the TMNT meet my 'Humanimal' Characters of Space Beasts, and the ensueing Culture Clash, in fact I think I was aiming for Culture Clash The Fanfic

Inspired by reading the TV Tropes entry for Under the Northern Lights, I liked the idea of Furries clashing cultures with other Furries/Anthros, so I set out this fanfic in mind with What would really happen if the TMNT met my characters? And hopefully what happens is not everyone instantly gushing over everyone else.

This has been a surprisingly popular fanfic of mine judging by how many faved or are following it

To the Tropers I humbly ask for your opinions, on spelling and gramer I know I've made mistakes in those areas, but to anyone who can get around those...I want to know what people think of the story, ae the characters as in character as possible? Is the romantic subplot believably written? I admit in my younger years I was about as cliched as any other pre-teen fanfic author...I'd like to hear from tropers if I created a believable fanfic that if not quite Original Flavor was at least a good read.

Did I do something wrong? Did I offend someone?

It sometimes takes time for them to notice.

Culture Clash is now a complete fanfic
