Quote from Omega

Actually, I thought the movement of the arm was rather smooth.

Everything else is terribly out of proportion with size change and shakiness.
Keep on practicing man.

After you get good at the basics of fullbody, add different shades of colour and start focusing on details like fingers and facial features.

Quote from M3D

I see improvement.

But you saying you have no tablet is bullshit.
Some people, Like myself, doesn't even have a mouse, [I just use my laptop] and look at my anims.

Good try. Getting better.

major resizing, major not right proportions, and major weird placement of the eyes

MAJORLY

Quote from Mesmay

Not having a tablet is no excuse, really =P
I dont have a tablet, I use a laptop pad too, and so do several other people.

Instead of repeating what others say, ill say something else-
try, perhaps, to try something other than fighting movements, after all, the best and most memorable fb animations are often not fights. Also, dont put your name at the end of every anim, it gets kinda annoying =/

Its far more tasteful to just keep it in the top right corner (small font) all through the anim. Even for shorts.

I hope you carry on with your fbs too, you're going to get better if you just keep watching others, keep getting inspired, and just keep trying. =D
