I have a "Stages of the aquascaper" article I wrote some years back.
You will find it useful.

I think the main thing is to look, try, and do.

Experience is everything.
No practice, you will not get better.

Just like any art, if I do not practice bass, I will not get better.
Practice is the main thing here, not an article on how to, although it will help.
