Hi,
You have a nice eye for compostion. I agree, it is time for you to go digital. After you spend the money on the camera, then you don't have to pay for film, or developing, and you can do your tweaking in photoshop with ease. You don't waste shots because if you don't like them...delete. Easy as pie.
And...get a camera that you allows you to change the lenses. Point and shoots are fine, but with your eye I think you will want more versatility.
If you have time, check our our pbase site. (My husband and I are avid
shutterbugs).

Again, your photos are great. I hope you consider going digital.
Cheers!
