What I make for your series

Audiences fall for a character, and notice the moment it stops looking like itself. Continuity is where the work is.

Negotiable price: tell me what you need and I’ll quote you. I deliver fast and in volume.

How we work with your series

Original, licensed and approved by you.

  • A style of your ownWe don’t imitate the style of living artists or studios. We help you define a look that belongs to your series.
  • Voices with consentVoices are used only with the consent of the actor or owner and a usage licence, and you are warned before it expires.
  • Rights agreed firstOwnership, formats and third-party licences for music, voices or assets are set before production starts.
  • Nothing moves without youEach stage waits for your approval, and AI-generated material is labeled.

Before you decide

Frequently asked questions

Do I need to know animation software, rigging or nodes?
No. You describe what you want, choose between options and approve. Eduardo handles the technical side, including rigs when a service needs one.
Can you make it look like a famous studio or anime?
No. We don’t copy the style or characters of other studios or living artists. We help you develop a look of your own.
Who owns the characters and episodes?
Your series is your project. Ownership, formats and any third-party licences (music, voices, assets) are agreed in writing before production. Your website and domain are yours.
Why are some services quoted first?
3D, rigs, lip sync, dubbing and music depend on the model, the scene and the licences involved, so they start from a minimum. You see the scope and the quote, and accept it before any work starts.
Do you use AI?
Yes, directed and checked against your approved references. AI-generated material is labeled.
We are a larger studio or a brand with several characters.
You can request a scope for your volume, team and calendar. Write to me.
