No worries mate, looks much better. Have a tinker anyway with the settings, as they will be scale related depending on your scene size units etc. Every model you do will require a different setting if you want a good AO output. Its not just a case of apply and render. You could increase the AA again to 1 and 3

Overall real good. Wires are looking good too, nice and clean.....

ahhhaaa....something you'll need to get some practice on if you wanna make better zbrush sculpts in the future......hardsurfaced or organic, its just about the quad but its about the edgeflow they have too

cheers
