Sci Fi Grenade

For my portfolio I wanted to make something different so I decided to make a round grenade.
In the past I had made a Sci Fi grenade but I wanted another variant of a grenade.
So I searched on the internet again and saw a picture of a concept artist on DeviantArt and used it for my reference.
The model is made in 3ds Max and the highpoly model in Zbrush. To bake the normal map I used Marmoset Toolbag.
I textured and rendered the grenade in Substance Painter. The background is made in Photoshop.
In the end I loaded the model and the textures to export the finished grenade for Marmoset Viewer.
I would be happy to read comments and critics.
