Poor Rumble had a bad dream and couldn’t get back to sleep. Good thing he’s got his big bro to shield him from the monsters.  
This idea popped into my head and I just had to draw it. I don’t think I’ve done anything with MLP’s best brothers yet.  
I may make this my style of humanization. I’ve got all sorts of ideas for it. I thought the skin pattern could come out when they summoned their wings/magic/earth pony stuff, sort of like kilala97’s humanizations. If anyone knows about the TV show Grimm, it would be kind of like when they vogue. I went with something similar to a peregrine falcon look for Thunderlane. The wings were really tedious to do, but I love how they turned out. Special thanks to those who made the tutorials I looked at (user links at the source)
