A bit late to the party, and its gonna be a challenge to complete this for sure... Well see. I'm not too familiar with LoL, but I'll go for a inhibitor and the creep den.
Concept is super rushed due to the short amount of time, but I have a pretty good idea of where I want to take this.
The hard surfaces on the inhibitor will mainly be stone and metal, as well as the floating crystal.
Time to start modelling you guys.
