what happened to his chin? for the love of god, where's his chin?!
now... presuming you did make the model (in which case, show some wires, and people will start believing you) 1800 polys is too much for a that head, you should be looking at having eyelashes for that amount of polys.
incase you're wondering why people are being so hostile towards your modelling ability, its because you've shown some very, very substandard renders and models (come on... spheres?) and then there's this quantum leap to an actual head.
Now, i don't have any problem with you using photos to texture a model, however if you're only using photos, you're gonna run out at some point, its better to learn to paint your own.
