I also do weapon and vehicle designs, especially back in my days as a member of the RWBY OC fandom. These days I just make my own designs but here's a few examples of some stuff I did for friends. I sadly don't have the full context outside of names, from top to bottom Blackjack, Kerberos, Taliesin, Ferrum Luna, Lumen Ostende, Tenka Fubu, Hippogriff, "Sniper Lance", Lux and Umbra
