Hey I like your art style, obv needs a little polishing, but if you put the work into it, I think you could make something happen.

...Mediocre?

Fun piece. Lip sync needs some work. When the mouth is closed (on "m" and "p"). Its usually good practice to steal the previous frame (i.e. start the closed mouth 1 frame before it usually would start), this will alow you to see those poses beter, during the animation. Also, your brain sees the cartoon faster than it hears it, so you usually push all mouth positions back one frame from when you hear it in the audio. All rules are open to change, but try these out and see if you like them. Hope this helps.
