Pari I suck an egg at animation. But yeah this is hecking sick, you nailed the change in speed after the initial break. I love how there is no pain just, an 'oh' response. Fabtabulous job, show more anytime you want fam.
Oh no no Pari is just kidding, I know a lot about animation but in reality I suck real bad man, I want to learn but my last attempt of finding a proper teaching environment kind of went side-ways.
1... Ha ha.
2... cool drawing
3... Why does the 0 have the / through it?
Overall, good job
But I'll hand it over to a professional for some proper criticism @calvinoot
You could also add some smears in to make the movement more fluide :)
