/ic/ - Artwork/Critique

I'm a clueless fuck but I want to start my own comic or manga.
How do I go on about drawing the panels for each page and what should be the size of the pages? Is it better to draw the pages traditionally or digitally?
I don't have a graphic tablet at the moment (just a regular tablet without stylus), so I only stick with traditional drawing. Most of the materials or tools I have right now are really cheap, but is it important to have a g-pen for it?
What are some good mobile apps and art books I can use/read for making comic or manga, and what are the other things I should take note before starting?
Also, how the fuck do I learn to draw the backgrounds/scenery?
