Hello Nat,
thanks for your work!
Very nice idea with the letters in this style above the mascot! Looks really good!
But all in all it looks a bit less colorful and I don't really see this mascot. On the one hand it looks cute, yes, on the other hand it is not really that animal or imaginery creature which comes to my mind when thinking of toddlers.
Hopefully you got another idea as well,
Tim
