I get your point, kaioshin. It's just that I believe that the theoretic approach as you describe it is not very productive. Personally, I did not learn of it as much as I believed I would.
Instead, if you want to learn to draw an eagle, google for 5 or 10 pictures of eagles. Look carefully at them and try to create an own one that comes close to the others, but is no exact copy of any of those. (Also, there might be tricks that other people discovered while trying to draw eagles.)
Or if you want to learn drawing sunsets, pick like 10 pictures of sunsets and create an own one in the spirit of the references.
Of course, the first pictures will not look as professional as the copied ones you are doing now. But it's a learning process, you will get better! Dare more freedom. Allow yourself to create (a lot of) less good-looking pictures, discover the flaws, practice new techniques and approaches, experiment with light and perspective, ask others for their perception of your picture... To me, this way was much more of a help than what I did before (what was similar to your approach). I just wanted to share this experience, because when looking back now, I see this time as a time of stagnancy from the point of getting skilled in drawing.
