When I first began doing 3D art.. especially in Poser with all the available free downloads and "props" that others have made, I too questioned whether this was truly my art or someone else's. Before Poser I used to do a lot of pencil sketching and "comic book style" artwork. At that time I never doubted my artistic ability. However, as I began setting up props and sticking one model here and another there, it felt more like I was simply photographing someone else's work. It wasn't until I discovered "post-working" and how much more can be added to a simple combination of lighting and props. This was where my true artistic talent shined, and this, I believe, is what distinguishes anyone from someone else. It's that personal touch they add to every picture. No matter the props... it's the artist behind it that can make the true work of art. My two cents...
