Although there are segments of animation that look pretty good, like land and water, it's clear they were not from the same animation house that did the storks. The overall animation is of the level of 20-25 years ago with limited use of camera techniques used in CGI films in the last few years. With most of the characters blend with the surroundings.
The story is sadly overdone and completely underwhelming. The sparrow that thinks he's a stork and a stork flock that doesn't share nearly enough screne time to believe or have emotional buy-in to the conflict that is supposed to be there.
Poor writing on top of that. Conscious animals don't know what a train is but are aware of puns, city names, and more.
That said, if you imagination only needs to be at a 6-year-old level, go for it.
