I realize these two are immensely obscure, but I adore them. Zayats in particular is the most incorruptibly precious creature in existence.
Volk couldn't help throwing himself out of a plane without a parachute if it meant harassing Zayats.
I know given Zayats' status as an infallible protagonist prevents such, but I think it would be funny if he'd just get really sick of Volk once in awhile.
So, relatively recent development: Back in either April or May, I discovered these two by sheer accident on a Sunday, and now Zayats and Volk are my favorite two characters in general. Nu Pogodi is a great cartoon, I highly recommend giving it a watch.
Linus is a mellow, kind soul by nature, which is why I think it would be immensely funny if there was just one specific guy who earned his genuine dislike.
Some sketches that came to mind after the Brave Locomotive color script was uploaded. It revealed some interesting details about the Von Kapital Railroad's contruction that the final version of the short cut for time.
I kinda found myself intrigued by the implicit idea of Linus' company in the roundhouse drastically changing over time.
A couple things I drew in the months leading up to the Brave Locomotive's release. I might have to come back to these at some point.
