Hey :)
First of all, I really really like your design, you did very well! I like that you've put your design also in the background. The mascot looks amazing too. But, I think that the "T" should be the same size as the "A" from "TONA" or the other way around. Also, you have some free space under those letters. But as I already mentioned, the most important element, the mascot, looks really great.
You should go on:)
