The edited pic doesn't show up for me, in that last post.
I think it's promising that you can take the criticism and carry on improving your craft as you've been doing.
An uncle of mine seems to have made a fortune (near millions I think) as a photographer.
I asked him if he'd have some tips for me to remember, were I to ever take it up as a hobby, or more. The gist of his reply was to stick to film, for the near future at least (digital cameras apparently are made for a short lifespan), and to do black and white.
Taking nice pictures, aestheticaly, wasn't the skill I'd have to learn most, but knowing what was going on, and anticipating what was going to happen, so that you'd have your eye through the lens and finger on the trigger when the "right moment" happened.
He said he didn't even look at and develop his pictures, till days or weeks, sometimes months after taking them.
