he looks fine in my opinion, but my standards are quite low but thats me. like ScootyPuffJunior said does not really ring "librarain" more blues would make him stand out more.
on the Positive sides I like to see that your tried highlighting him even thou its a bit thick. He is kinda interesting too look at thou in a way. For your next model I would start working on thinning your paints and making highlighting softer. Just little bit of highlighting makes a large difference.
Is the robe custom? cause it is quite nice.
Overall: Not a badly painted model in my eyes, but not a amazing model. Still looks nice thou. I have seen worse models, (my first batches had only 3 colours

).
