New Story Idea: Horror part 2

As promised here is the next development in My story. This time I decided to Bullet point the three different acts and try to tone down some of the details, whilst retaining the same themes as the original draft. 

 Act 1:

• Circus Appears in Town Overnight
• Creates an unsettling/eerie vibe in the town
• Two sibling's and Mother Enter
• It's quiet, seemingly abandoned
• Faint sound of children singing, echoes around the grounds
• Approached by the owner of the Circus owner
• Whisks the parent away
• Children are drawn to a monolithic Bouncy castle
• Enter the doorway and the world goes black.

 Act 2:

• Children awaken in a dark workshop (Half stuffed animals lie everywhere, a layer of dust covers them)
• Reams of thread is strewn across the ceiling and floors like spider webs.
• A faint bulb beings to swing 
• Tiny pattering can be heard, the two children back into a corner, sister shielding brother.
• Dozens of little voices giggle and whisper in the darkness.
• Wide eyes and smiles fade in around them
• Voices begin to hum, "I've got no strings on me"
• Song gets louder and louder then stops, as heavier footsteps appear,
• The footsteps get closer and closer
• Taxidermist appears out of the void, barely lit by the failing bulb
• He inspects the children then whispers "Welcome to the Family"
• The light goes out. "Meet your brothers and sisters"

Act 3:

• A group of what appears to be children begin to clamber forward, over each other
• Twitching and spiraling, falling as they move. (each child, scarred and stitched together, Electrodes protruding from their skin)
• They clamber over the two children, clawing, biting, separating.
• Both brother and sister are strapped to tables.
• A bright light hangs above, blinding them
• Taxidermist stands over them, produces a knife then smiles. The camera fades to black as screams are covered over by humming and laughter. 

As always some feedback would be really appreciated, as I want to get this component out of the way as quickly as possible and start designing.
