Looks ok, but the crazybump normals and photo sourced textures are really not doing much for you. Almost every spot on the model where one material meets another looks really bad. You really should be modeling and sculpting a high poly version of the model to create the detail you need for the low poly version. Simply pasting photos onto each part of the model will not yield professional looking results.
