Nicely done man! I belted out a low poly version of the vulture variant for my midterms at school. How many hours did this take you to do? And what program did you use? I made mine in 3ds Max.
I have no Idea how many hours I've used. I've rebuilt this model twice after I made the first version years ago. I never keep track of my hours anyway since I have no need to do so. I used wings 3d.
