Thanks for the tips! It looks like I took those at f/5.6 and 18mm, so I could have opened it up to f/3.5. Not sure how much that would have changed the shot though. I was thinking more about getting a sharp image when I took the shots, so I was trying to stay away from being wide open. All things to learn to think about! I'm still a little limited in shallow depth of field with the kit lens.
