Hair patterns for the one on the log don't look bad.. Looks like the eyes could be sunk in to the form a little which would help with the eye shape.. Ear shape is off.. you really have to watch them as they dry.. Careful with how you are bending the tails on both squirrels especially the one laying on its back.. They dont just all of a sudden kink.. Google image squirrels and get some good close ups of the face.. Good starting point though
