More GreasePencil Animation mixed with 3D overlay/rotoscoping

I modeled stairs in 3D and drew a guy smoking and walking over it.
animation is time consuming and hard. the more i try it the more my respect grows immensely for all the amazing animators out there.

this one is like the punch animation except I removed the 3D part of it from the render and drew over the pieces like a rotoscope.
