Doom Style and technique learning (highpoly)

this model is based on the artwork https://www.artstation.com/artwork/eZenG by the amazing artist Colin Geller.

With this model I was trying to work understand the shape design of Doom.
I used boolean operation and round edge on the final model everything was done inside maya.
I was curious just for the main shape proportion the other detail I can do them with smaller trim decals or paint them directly on the normal of the low poly.

While working on big projects that require time to finish I like to doodle sometimes on some specific techniques that I want to try and learn.
