Hi Diane, Welcome to CiC.
I like #3 for its lovely composition, I would crop a little from the right.
I think others have covered posting adequately and thus will not go there.
You probably should have used a lower iso setting to reduce the noise level. Doing so would require a longer shutter speed and would need to have stabilized the camera. A good tripod is the standard stabilizer, but you could have used a pillow, book, or whatever and triggered the shutter with a remote or timed release.
