6 Create a handful of variants
I’ve found that three versions of a concept is a good number of iterations. Although Riot tends to explore far more: for instance, between two concept artists, we created almost 100 tower designs. This is why it’s important to rough out ideas in sketch form, and not commit to painting anything until you’ve got a direction that your team is willing to invest in. This rule is up for debate, though. Most studios won’t let you spend a week painting one idea. A concept artist’s role is to serve your team. If you want to do your own designs, go and start your own game studio!
