Not trying to reply for the other Robert (Darklimit) but here are a few suggestions to add personality:
Cannot see a mouth in your post--does he have one? Does he have teeth? Fangs?
Does he have eyelids--It's hard to blink/sleep/emote without eyelids.
Check out even these simple emoticons (which I cannot seem to resist using in the AM Forum--very frustrating):
What kind of props will he interact with in your story: Chairs, rocks, a sceptre.
These all can add personality and interest to the story.

(Edited to add: "Rocks" where the heck did I come up with that one)
