Yeah just some pointers
Time8th is right but a few more hings you should know.
*One thing you probably need to get if you want better scores on this is a Tablet so you can draw a bit better.
*The story needs some work and you need to sort of equalize the sound.
*Some voice acting would never hurt (Well I should say might not hurt but in this case add some background music or light voice acting like a narrator.)
*Ummm you might want to fiddle with some showing too.
*And it seems for most of your effects you use a shortcut which does bring down the quality more.
*And I did not see much of your doctor in this one either.
*Just keep practicing and you'll get even better at it.
*And again try to avoid shortcuts.
GOOD LUCK
