Hmmm... I think for me I lean towards realism (=quality). It can be an evocative or surreal image...but it's how
it's done... and I guess it's whatever makes me 'tick'... but I'll prob not vote for something experimental unless I think it's worked - or a quality attempt... humour is also a big 'draw' for me, pardon the pun...(just see some of my hilarious attempts at trying to chop!!!!!
I'm not that excited by blood n guts but hopefully I look past the 'subject' in those cases to the overall effect/rendering. I'm also not overawed by an image that just has a plug-in or filter effect over it...I like something that seems thought about.
Since I came across this site several days ago, I am aware that I am trying styles that I maybe normally wouldn't want to or be able to work with - so it's great to have that freedom...
I guess it always comes down to personal opinion but I'm guessing that a bad chop will always get less votes than a good chop...so there's always incentive to improve!
