Cute:)
The animation is way to slow, especially on the bat swing. Taking out some frames might help. Also adding a shadow casted by the ball would also help in reading the animation.
Overall it's a cute piece:)
the way the ball moves is quite weird, maybe it should be faster, but its really cute anyway. ^.^
thanks [:^) you have good eyes for pixelart . I'll try to create this type of impact on my upcomming uploads. this thing i just picked up from my portfolio which i have created in 2005
