All fine shots. Of course, everything we ever do, including photography, could always be better in some way.

I'm not sure what setting you had on your camera...but... try setting your camera to Aperature priority. Then, set your exposure as you like...and let the camera automatically choose the fastest shutter speed for you, given the amount of light that is available..

I am assuming that you are not trying for some special "blur" effects, of course. I always figure the camera is smarter than I am, anyhows. Keep them coming!!!
