The mapping looks very generic and bad. The gold color is terribly shaded and pixelated. There is a seam going down the center, as you mirrored it incorrectly(you didnt stretch the line a bit past the center), and it looks like you did not even reverse the angle of the effects you used on one side.
Overall, its pretty rough, but it has potential if you fix all the mistakes. You really need to work on how you mirror stuff, as its very shabby. The shading isn't outrageously bad, but I don't like it.
Before you continue the head, I suggest you buff out the small issues, such as the seam, and fix the mirroring.
5/10.
