Your traditional is better than your drawing by mouse.I recommend getting a drawing tablet one day if you want. It's great for easier control and handling when drawing on the computer.
As far as traditional goes, I recommend trying to copy some drawings done by an artist you admire.
Just have the picture up on the computer and do that drawing traditionally.
Compare both pictures and fix your drawing, make minor changes if you have to.
I believe it helps you practice until you believe it's absolutely perfect in your opinion.
Obviously you wouldn't have asked for help if you didn't think it wasn't perfect.
Take your time, dogpaw. It takes a lot of patience and it takes a lot of time.
If it makes any difference, you're a way better drawer than me. xD
Oh, also find a scanner. Ask your parents if there's one in the house that you can use. Because it would be better quality than just taking a picture from a camera.
