I don't know what map size you used, but that texture is really blurry. Something I do to avoid that is to do what you've done overall, which is get a general gist of the features, but then I'll go in close for a little while and detail out each individual area.
The colors you're using + the blurriness kinda makes it look cartoony

Like I should talk



Also, you're details aren't showing up in your normal map very well. Did you use a sculpting program to create it or is it hand painted in Photoshop?
