Male Base Mesh 3d model

Hello, I have been following you from cults3d I really like your work. My name is Aphiwit Thuengrat, nickname Gun. I am from Thailand. I graduated in interior design, but I am interested in tattoos and want to be a tattoo artist. my tattoo artist name is “ironlamb”I am going to create a tattoo in a 3D metallic style. I can create 3D models, but with objects or animals, it takes a long time to create and it is just a duplicate. I am looking for a website or source that can take those 3D models and change the material into a metallic style.“ironlamb” started by making existing objects into shiny materials like iron or metallic.I am here to ask for permission to use your 3D models to further develop my art.I'm curious that I take other people's 3d models and turn them into new materials and use them as tattoos. Is it copyright infringement?I understand that the artwork that the artist created must be requested first.But models such as tables, chairs, dogs, cats, chess, balloon dogs, things that already exist in this world.Is it copyright infringement? And do I have to ask permission from anyone? Because everywhere there are models that look the same.But I am just worried that the tattoo design that I created by modifying from your 3D model will be Copyright infringement for my brand. If so, I apologize. I did not intend to think badly or claim credit as mine. I just modified it. With respectAnd here are some of the works that I created. Some I sculpted myself and some I downloaded and turned into metallic.I really want to upload a picture of my work for you to see.I would love to send you pictures of my work so you can see and imagine it. Can I have your email? And yes, it is to bring 3 models to change materials and render them into images for tatto design, including the cost of buying tattoos on the skin.So that means I take your 3d model, transform it into another material, and sell it as a tattoo art, it’s Metallic style main style of “ironlamb”It's not copyrighted forever, right? I'm here to ask for sure if i use to make my art tattoo.🙏🏻🙏🏻
