C&C always more than welcome.
Why would I choose this? It's not overly interesting, nor that well composed, but I liked the colours (strong yellow and red with the pale / pastel green of the plant to the left). I'd have gone for better framing, but I only had a t-shirt on, it was getting very nippy, and the sun was about to go down. May go back to get a more interesting framing tomorrow.
You've listed six reasons why the pic isn't as good as it might be, so you've kinda provided your own C & C...
I don't want to comment on your pic, but, for me, a pic that 'works' is one for which I don't have to make excuses ("If only..."). Colour, tone, composition, exposure, quality of light, etc: all have to come together to create a successful image. It takes a bit of time and effort... and that's both the fun and the challenge...
