ok so im going to carefully explain to you how to fix this and i want you to listen to me
1) buy (or pirate i dont really care) adobe animate
2) repeat step 1 for adobe editing software(s) (after effects, etc)
3) learn how they work
4) learn to draw with a mouse (prefered) or buy a $300 drawing tablet (i really wouldnt recommend that) (also learn some editing and a little bit of fl which you can get too)
5) practice for about a year
6) post results
