I would like some advice on using Photoshop for my drawings. I'm trying to improve my coloring skills and was hoping if anyone ccould help me out. But there are a couple of things that I really need help with:

- How can I easily outline my drawing? (I tried using a marker, but it would always turn out lighter when I scan my drawing.)

- How do I make my images look less blurry?

- Do I need to layer my coloring?

I would really appreciate it.
