This is my two first sculptures. They are 2mm steel sheets welded together. The piece on the right one is the first one I did. On this piece I chose to grind down the welds and paint it, but after the basecoat, I wasn't really satisfied with the piece, it didn't really look like steel anymore. Therefore, I made a new one where I kept the welds to give it a more industrial, tuff look. The first one will eventually be sandblasted to regain it's metally look.
