It's a far more fluid attempt than what I usually see from others experimenting animation. It really is a pain to do well and is why there are a bunch of noticeable shortcuts, including minute-long efforts that are just two seconds of unique animation stretched out with image manipulation (close-ups, flipped versions, copy/paste'd... usually in groups of three or five) over some fun, copyright-free tune. It might be easier to create simplified variations of your OCs along with some comic panels to tell a story and then pay an animator to create some in-between frames to turn that into a cartoon... or just focus on your art and let the viewer's imagination do all the work. Perhaps if something down the road really speaks to you, the added effort might be worth the trouble to bring your vision to life... for that specific thing.
I very much doubt anyone would mind seeing the logo. Artists are not commonly known for having money to burn and if animation is not a priority, then paying a premium to do so would be kind of silly.
If you ever decide to attempt animating something to completion in the future, maybe scale it down to a small set of emotes. Just some simple collection of facial reactions or behaviors. Even I've done that much and only because I had friends too poor to pay for an actual artist to make something for their streaming channels. Begin slow, then let it grow... or whatever. IDK. I'm not an artist.
All in all, an effort was made. It does not look bad for what it is and I hope you're proud of yourself for not giving up.
