"...make sense?..." you ask
Totally!
Dew, you may call yourself an "amateur" but i see you are already thinking like a professional shooter: "concept" is important, without it one is left, at best, with just a lucky shot
Good to see you aren't scared to shoot in the rain - a time when colours are most vivid
In answer to your question of "a good place to start," my suggestion would be to start with all your out-takes. Don't delete them, rather - download them to your computer (i noted you shoot digital) then study them long and hard for they will be your greatest teacher
See what works (and why) look at what doesn't (and why) - and grow from there
If possible, keep a record of exposures, readings and settings for each shot and use this when studying the work
Something else i'd suggest: study the work of others, maybe get some books from the library or use the Internet; look at what works and try to understand what the photographer has done to achieve their shot
And - don't hesitate to post back if you want help with any of the "technical" bits
You are well on the way to achieving the image you want...
Good stuff!
