I saw one of the riot arts as miniature for this update and thought "what? This can't be modern interiors". Apparently it can! Funny that I saw this update after seeing and buying the exteriors ;)
Working with Riot Games forced me to draw pretty huge buildings, totally out of my comfort "sprite size" zone! Thanks to that experience I feel way more confident now with all the exterior stuff and I'm pretty sure I'm gonna draw some very big buildings for Modern Exteriors too ;)
