Now that I've gone over my beach/boardwalk shoot photos, I definitely see that a lot of the angles are repetitive and unvaried. :3 I will definitely try to be more creative with angles!
I've currently got the Canon Powershot SX230 HS, which I haven't used in a shoot yet (haven't taken any real photos), and I hope this baby will be with me for a long time. If I find a camera that's more in-tune with me than the Powershot, I'll take your advice and save up for the better camera.
I just googled some links about fill-flash. Didn't know that existed. XD I was never a fan of using flash, but now I see how fill flash can help brighten up a dark subject.
I'll study more about it and hopefully become accustomed to using it for situations that require it. Subtle flash sounds nice.
Imaging resource says this for my Powershot:
Maximum aperture at wide angle is f/3.1 and f/5.9 at telephoto.
I guess I'm set! XDD
Thanks for all your tips/suggestions! I will keep them in mind. I'm researching online about fill flash and aperture as I type this. Lol.
