He was afraid to throw punches. He didnt have any killer instinct so he was focusing on a gameplan instead of actually using fighting skills. He didnt really throw anything on the feet, and at one stage he had his opponent's arm pinned, opening him for viscious elbows, but he instead looked for another position. His mind was only focused on one thing, and that was getting the mount. He never throught about working his way in or setting things up.
I'm not really one to say "It was good for his first fight". In your first fight you want to excell in one aspect, like striking or BJJ, and then you can advance forward from there into a more well rounded fighter. Batista didnt show any skills in any area really. Still will be interested in his progress though. I see him being triangled or guillotined in his next one.
