Yeah, I agree. I may go back and try to do so-it's just a lot of work that I'll have to do for each frame (and I'm lazy) but shouldn't be too terrible. It's also why I haven't uploaded the other front sprites yet, due to having to think it over haha
I love this little guy - both like, in the abstract (he's a very cute design!) and in this particular rendition, which imbues him with personality that the canon games don't really. Makes me want to try some Crystal-like animations.
I do wonder whether you couldn't upload all these Duckletts in a single image, though? Having the shiny form separate is a bit weird.
I love the way the head angles to the side. It adds so much character to this charming animation.
