What combination of god and man is Gilgamesh? And how might this combination affect him as a leader?

Gilgamesh is 2/3 god, 1/3 man. According to the prologue, Gilgamesh would be handsome, courageous, strong, and intimidating.

"When the gods created Gilgamesh they gave him a perfect body. Shamash the glorious sun endowed him with beauty, Adad the god of the storm endowed him with courage, the great gods made his beauty perfect, surpassing all others, terrifying like a great wild bull. Two thirds they made him god and one third man."
