Your character has a great potencial. Looks amazing. I dont know if you already have an idea of the illustration. If i may suggest , the small human legs got my attention, could be a way following a human action and fill with the monster movement. Something like a gladiator fight when you use a wall as a support for an attack, you know ? If you look at Monsters Inc pixar movie has a sequence with a big boss that looks like a spider or crab. Maybe could help for future ideas.
See that as one more option on your deck.
Good luck to your character.
