Gray metal with a small geometric coating plus bright gradient details create a sci-fi weapon style 70's 80's. Original sketch did not look like the final work, this is accompanied by multiple improvements. Weapons 70's 80's were not very colorful or too bright, they are more likely to have been some bright detail, or constrained geometry, which gave them the originality of this or that weapon, im try reflect those concepts in our work. Maybe im wrong, and will try to do something different in new my work.
