Rolling Logs

If I may,

A great effort at capturing this squirrel, I know these guys hardly stay in one place for long enough. Fidgety little critters they are. Its really great that you have got the squirrel in sharp focus. The composition is also interesting. the curve made by the squirrels body mimicks that of the trunk.

But what isnt working in this image is, the quality of light. This image looks like it was taken in hard light, and hence there are some very strong shadows, and the contrast seems to be very strong. I might consider a B&W version of this photo. Another reason why I might consider B&W is because most of the image seems to be the different tones of the same colour.
