Good first start.
Did I like it? A little. Was the art perfect? No, but some parts it really shined through, and I could at least the video. But as you state this is the beginning, which is to be expected, this is your first and you did this because you love it, nothing more. Did I think the sound effects were louder than the voice overs? Perhaps. But I can see that this was some hard work, which is always commendable. The story was interesting enough that I was willing to watch the whole thing, but sometimes it got hokey enough that I kind of cringed. Does that mean it's bad? No, it just means that it wasn't my cup of tea in certain areas. At least for the tournament, that is. I find the whole tournament story line to be slightly tired and over used. Past that though I found interesting and quite enjoyable, story wise.
So what do I really think about it then?
Like I originally stated, it was a good first start. I think in some parts it could've been polished more; the voice acting would be one point I'd fix, though that appears to be technical error rather than a specific persons. I would also focus on trying to not reuse a lot of the movements for talking (you how you kind of just shifted between two or three faces to make it appear as if it was talking?), it is perfectly fine in the beginning stages of this, but later on try to work on not reusing particular frames. Liked the story by the end of it, enough that I am willing to look into the next episode as soon as it comes out.
7/10, 4/5, and a heart felt encouragement; you need to keep doing what you want, and not let others discourage you. In fact you should rise above what they think of you and come back with a bigger, better, and overall shinier episode that way you can rub it in their faces, knowing that you didn't give up and you rose above the hardships.
Good luck in future endeavors.
