3D character designer for video games.

I need a 3D designer to work in the long term, we have a base of characters which we want to add new ones. Characters must be adapted for a unity-based game.

The character reference is as follows: https://assetstore.unity.com/packages/3d/characters/humanoids/fantasy/casual-tiny-character-ninja-pack-169234

Please check the reference before writing, automatic responses are annoying.
