Paintings
There is no theme to this. It's just paintings I've made.
Samus Aran from the Metroid video game series. This version of the Varia suit is from Metroid Prime 3.
This is the M41A Pulse Rifle from the movie Aliens. The design is timeless to me and I really like the sound it makes.
Scrooge McDuck. The richest duck in the world and also a badass adventurer.
