One of the Steam Community Workshop submissions I worked on for the game DotA2 by Valve. The base model belongs to them, I simply created a 3D model of an armor set and minor elements such as extra bits of hair, tail and horns. Since the model doesn't use a sculpted normal map but a hand drawn one instead, it looks far from decent. Nonetheless one of the most extensive projects I took alone. Learned a lot about 3D modelling which I do not intend to get professional about, but knowing what the 3D modelers I intent to work with go through is invaluable. The set was not accepted, though I never really expected that to happen. The experience was the reward alone!
Here is the promotional video demonstrating the 3D armor set in-game.
