host it in www.antiup.com cuz sometimes some people cant see i some pages
1.-Resize (the stick changes too much his size)
2.-Choppy(It Lo ks Ch py make more frames)
3.-please don't make 2 sticks in one frame (when he's jumping in the hole)
4.-make a stick in every frame (6 frames after 2 sticks)
5.-dont let random dots let out (when he's going out the hole)
see the tutorial section, learn about basic movements ,easing and soothness
use a tool called "onion skin" (look it up on google or something)
it's basicaly a tool which you can see past and future frames with 50% opacity, so you can see the last frame as your drawing the next one, it helps a lot with resizing, smoothness, and overall general animation.
also try using different layers to keep your animations clean. ;)
and about you using a mouse, most people here use a mouse lol, i use a laptop touch pad, dont know if anyone else does. =]
i used a mouse for a year and a half doing full body, some of the time and i didn't think it was that bad, till i compared it to a tablet...
and i suggest you look at tutorials on basic movements ,smoothness, and try onion skins for resizing, i don't think i would want to animate without onion skins.
