it looks like a decent start, is your normal map green channel inverted or something, the lighting looks odd in the angled screenshot

Nice start

Though like @Ged
said

Lighting is off

Decent first sculpt!
Don't light things by just adding more white or black.

See color changes as color temperature changes.

Decent guideline:

Things that are in light, get warmer in color temperature. (More yellow/white)
Things in shadow get colder in color temperature.  (More blue)

Its too noisy, Add less random damage and more detail that would make sense Have sex with your reference. If you dont have any Look at Orb's work in Crasher to start.

Grab Orbs Brushes if you dont have them
Play with OrbFlattenProtect and the Mallet fast brush within the light box
