yeah the texture looks a little jagged, but i figured the ingame looks solid so i was easier swayed to saying meh...it looks good in game and that's what matters. BUT....seeing as it's been mentioned twice, i'll blend it a little better.
Definately fix the sides - the cyber should look good straight on, as you have in your preview pic, but also the side views of the face, must all tie in and blend in good.
