Looking really nice. One thing that I notice is that there seems to be a slight noise in the normalmap on the pure metal parts at the rear of the turbine which makes it look almost concrete like. Generally, you don't need a fine noise in the normal on metal surfaces because it makes it look less like metal and more like concrete and other types of surfaces. Put the noise and variations and scratches on the specular map instead for a better effect. If there are big dents and deep scratches you can of course put them in the normal but for smaller stuff, specular and diffuse is usually enough.
