class CreatorRawArtworkSerializer(serializers.ModelSerializer):
        collection = DesignerCollectionSerializer(read_only=True) #assuming you have already defined serializer for *DesignerCollectionSerializer*
        categories = DesignerCategoriesSerializer(many=True)

        class Meta:
            model = CreatorRawArtwork
            fields = "__all__"
            depth=1
