"The Thornthwaite twins had spent so long trying to kill each other that neither twin could remember which act of attempted murder came first."

The twins for #NationalSiblingsDay (I still need to draw their younger sister, argh). One's a hero for hire, the other, an agent of the Empire. They kind of hate each other. Surprise! #swtor #swtorfamily
It's #NationalSiblingsDay, and today, there's strength in numbers as sisters unite to take on their mom!

Oh my swirls, it's #NationalSiblingsDay! Tag a sibling who always has your back!
Throwback Artwork for #NationalSiblingsDay My sister taking my hat. 🤣
It's #secondhandheroes 3's #bookbirthday and it is also #nationalsiblingsday. Brothers Hud and Tuck share a moment right before they head into certain death. Their relationship was based on me and my brother. I may or may not have used water from my own tears when painting this.
Happy #NationalSiblingsDay to my big sister who is wisely not on Twitter! Couldn't ask for a better weird science sibling. <3
