Papa - (waving at Philly - I'm a bit homesick - doesn't happen often!)
I would not classify myself as artsy as some and in real life (outside of photography) I am not creative or artistic at ALL- but since I've had my Canon S2 - I find myself coming up with some pretty good stuff - in my eye.
You need to look outside the "box" - look at things really close up, look at things from an different angle - lay on the ground stand on bench, etc - you get my idea -
Look at the big picture and then focus in on something small but interesting - shapes, colors, textures, etc.
Some other folks might have more "technical" advice - but all of my "artsiness" comes from my heart or what makes me feel good!
The beauty of digital is that if it doesn't work - you haven't wasted anything. Get out there and play!
Good luck!
