At first I've tried to make my monster very dark using purple and blood red.

I've added blood puddle so i could make it even scarier.

I was totally going for..

this i guess. 

ok.. it is a bit scary.

Then i thought it would be too much because monster house is a kid's animation

well I don't think so but a review says it is so i changed my concept

I've changed blood puddle into a cotton by adding more to it using my brush,

cotton on the couch arm is bursting out.

My concept was an old broken anthropomorphic couch abandoned in a monster house.

Old sofa (referenced color and the texture)

broken spring

What I have to do: 

I'm planning to create this couch opening up a mouth.

I'm thinking of fixing the teeth into a broken wood piece

so it is sharp but has the wood texture so it looks more natural as a couch.

the reason i thought this was because in monster house movie 

you can clearly see that the house it self is made out of a material. 

so his teeth is made out of wood,the hands are trees, the eyes are windows.

and the head are made out of roof tiles.

I might just do a brief sketch before i go further just so i know what to develop clearly.
