-- Get available head shapes for the user
local headShapes = AvatarEditorService:GetHeadShapesAsync(userId)

-- Create a BodyPartDescription for a Dynamic Head with a Classic shape
local bodyPartDescription = Instance.new("BodyPartDescription")
bodyPartDescription.BodyPart = Enum.BodyPart.Head
bodyPartDescription.AssetId = dynamicHeadAssetId
bodyPartDescription.HeadShape = headShapes[1] -- Apply the first owned head shape
bodyPartDescription.Parent = humanoidDescription

-- Apply the description
