Forest Inktober Day 6: The Ancient Robot

I'm following dropthedrawings forest prompt list this year.
I was thinking a peaceful forest guardian robot made of stone instead of metal and powered by crystals. 

My inspiration for this one was a mix of the Iron Giant, Bastion from Overwatch, and the vehicles in Atlantis. I'm really happy with how many people have been able to pick it haha. 
I'm glad I managed to make it look friendly instead of scary.
