I forgot to say. One of the really, really hard things about creating great images is being able to look critically at your own work, epecially if your family and/or children and/or pets and/or places of significance are involved. Cue photo of cute baby growing a lamppost out of it's head. We are so good at only seeing what we want to see, someone without the emotional attachment comes along and looks past the cute baby to the lamppost, distracting background, overexposure and poor focus!
So, I'd recommend this Flickr group to you:
Flickr: Photography Critique
You will probably want to lurk for a while and read what people are saying about the images before starting to contribute, but it has great potential for developing what is probably the hardest aspect of photography - not the techie stuff, but the 'seeing' arty side of it. Technique is simply the tool to achieve the ends, not the end itself.
Well that's my take on it. Of course having the luck to be in the right place at the right time helps, but as a famous golfer is alleged to have said, 'the more I practise the luckier I get'. For my money an artistically stunning image with so-so technical image quality is far preferable to one with fabulous technical image quality but which is boring and/or compositionally flawed and/or needs a bit of post-processing to 'get there'.
