Element Grenade

For the final exam in school I learned how to make a complete asset in two hours.
This element grenade is one of the assets I made for practice.
First it was only one grenade but I had the idea to make more variations of this one so I decided to make more textures for other elements.
In the end I made five different variations of this grenade.

The model is made in 3ds Max and the highpoly model in ZBrush.
I textured and rendered the grenade in Substance Painter.

I would be happy to read some comments and critics.
