To make smooth camera movements!
Of Course!
First of all you get better by practicing, even if it’s just a few small doodles a day. Looking at references has really helped me, I recommend Pintrest for ideas, references, or just cool stuff in general. You can also watch videos. For blending I recommend using a blending stick and if you don’t have that you can use a tissue or something soft to blend
Sorry I thought I was answering :}
True. Drummers and percussionist are the main source on rhythm other than the director or conductor.
With love,
