Congrats on getting photos of a chipmunk – those guys know how to move pretty fast so they don’t make it easy to take pictures!
A few quick thoughts:
-I would crop in on the first two to focus better on the chipmunk. I think it would also greatly improve the pictures if the chipmunk wasn’t centered but was on a third, which is thankfully something you can fix in cropping.
-The third picture is great – not too many distractions going on (other than the stem of the leaf sticking out in front of the chipmunk) and nicely zoomed in.
-In general, the photos strike me as being a bit grainy and the chipmunk’s eyes not quite tack sharp in focus. Again, I acknowledge that chipmunks have got to be hard to photograph, but if the eyes were more in focus it would vastly improve the pictures and give them more of a “WOW” effect.
Let me know if that all of that makes sense or if you’d like me to better explain anything I said 🙂
