What type of sculpture cremation urns are available?

My husband sadly passed away this week. I’m now stuck with the difficult decision of what urn to choose, as I’m having him cremated. He was a gifted artist, so I’m looking for a creative and different type of urn for his ashes. I really like the idea of keeping them in the form of some kind of sculpture, but I don’t know much about it. Could anyone please explain what types of sculpture urns are available? I’d really appreciate some guidance.
