LEGO Moc designer. You can find some of my projects on LEGO ideas: ideas.lego.com/projects/81d82dbb-5059-4687-a065-4909cf677225
I mostly use Bricklink's Studio 2.0 cad software for designing and rendering my projects. But I also use real bricks too!
Also... I'm no photographer, so sorry for my amateurish photostream!
