Interesting intro, neat animation and good use of the zoom and blur effects, hope to see the firs chapter of this project that you're working on.
Well, I'm looking forward to it. It looks well done and seems to be a Mario/Kirby: Right Back at Ya crossover which will be a nice break from the Sonic crossovers. I just hope you don't pull too many elements from SMBZ (even though this looks like follow-up series). I think you should also make Kirby talk. Mario and Luigi got away with not talking in SMBZ because Sonic and Shadow could talk and made the connection with the audience. I don't think it will work as well if Tiff is the only one of the four heroes who talks.
This didn't lower my score, but that song is getting on my nerves. I don't know what it's from, but it has been used a bunch of times in other sprite intro/trailers.
Forgive me if my comment doesn't seem too enthusiastic about this future series. After recently learning that SMBZ was cancelled, It's going to be hard to adjust. The intro was good, but it's too long. If you do plan to use though, at least just use it like in the first episode and shorten it for the rest of the episodes. Other than that, I say good luck to you.
Hmmmmm, it is interesting
Hey Shadow, you're still improving. (Looking forward to Shift, that preview was fantastic.) Not a huge fan of the music choice, but that's only because I'm picky and have no idea what series that's from.
