Hi! I am a freelance illustrator from Czech Republic, currently living in Prague.
I started doing freelance illustration in 2018 and my main focus are sci-fi and fantasy illustrations for board games, RPG books and trading card games. But I will illustrate anything that fits my style and favorite themes 🙂 See below for full refrence.
And in case you were wondering what a heck is wrong with my name… My real name is actually Jiří Kůs. Better, huh? 😀 That is why I started to use more english-friendly “Yiri Kus” 🙂

Pricing
I price every project individually based on my hourly rate ($22 per hour). An illustration can take anything from 10 – 40 hours depending on the complexity of the subject, number of characters, design requirements, reworks, etc..
For this reason, first thing I do when somebody wants to hire me as an illustrator is to give a price estimate and then we can either agree on fixed price per illustration or hourly rate.
