Trying out Blenders Grease Pencil for the first time. I really enjoyed working with Grease Pencil. The pen tool can be a bit unpredictable with a Wacom but the Line and shape tools are solid. I used BlenderAe to add the mattes to the screen and for the camera and empty/nulls for the clouds for compositing in After Effects. I also got my head around cryptomatte which are a fantastic way to create mattes in 3d.
