I'm generally supportive of young artists and their personal project, and I do wish you the best on yours. It's difficult to get a project off the ground, especially if you've never done one before and you're still figuring things out.
That said, I think your energy will be much better applied in developing your project instead of addressing criticism in a forum. Keep in mind that animation is a visual medium, and many people here are only interested in
seeing what you've been working on.
My advice would be to stop responding to comments in this thread and stay focused on your project. When you think you have something people will like to see, post a few images or animations either here or on your blog. It's also a good idea to define a few parameters for the type of feedback you want. Do you want opinions or advice on technique, design, concept? If you are just showing your progress and you don't want any public feedback, you can state that too. It won't stop people from commenting but this way, nobody will expect you to reply and you won't feel obligated to. The important thing is to give people something worth commenting on. Otherwise, it's just wasting yours and everybody else's time.
Regarding first projects, I highly recommend creating something very small. It's much easier to figure out an efficient and reliable workflow for a small project than a large one. If you can pull that off, everything you learn from creating the small project will help you carry out a bigger one in the future.
And when I say small, I mean a single scene running a few seconds is perfectly legit. Think of it as a mini-short or an animated comic strip: set up a gag, visual or verbal, and deliver a punchline. If you want to be just a little more ambitious, use three scenes with the same environment, and cut it wide, CU, wide. That should be completely doable in a couple of weekends, probably less depending on your designs. What's important isn't the scope and duration of your project but what creating one, even a tiny one, will teach you. And keeping the project small makes it more likely that you will be able to finish it, especially if your personal time is very limited.
FWIW, my very first 2D and cgi shorts only ran only 15 to 20 seconds in length. I remember getting positive responses, but I also waited until I was finished before posting the shorts. Granted, this was way back in the early-to-mid nineteen-nineties* so there was a lot less competition, but even back then I don't think I would have gotten any kind of response without having something to show first.
Anyway, stay enthusiastic and good luck!
