The minotaur is a powerful frontline mech. Using medium strength beam lasers on its wrists, it can mow down enemy forces. Weapon pods can also be attached on its shoulders, or equipment can be held in the mech's dexterous hands.
I love the upper body of the mecha; I think the shaping of the arms is particularly nice in the front. I think the only thing I would do is replace the bionicle leg pieces and use a combination of parts to have a knee that can bend. Just a suggestion, of course! Keep up the good work!
