I like the way the tail is covering the back...... the lines of the wound where a branch once was is interesting... I would have picked a different monochrome color but that's my own personal taste
Cute! That made me smile soon as I saw it. Titles DO help! Nice composition with positioning of the subject, and the tone you choose helps. Sky is a bit washed out, but not a major impact since there is little sky in the image overall.
I like the texture here and the sepia treatment. The moment in which you captured this squirrel fits with your title, as it seems anxious and pensive, like it discovered it is recently missing something important. I think that without the scar from the broken limb, this would still be a good photo, but not as appealing and not nearly as interesting. A well-seen scene. Good luck
