After a very, very long and somewhat-needed break, I came back to rendering the spine with renewed motivation. Here they are."From the front" isn't an optical illusion, and it is, indeed, crooked. It was the first spine that I had completed, when I blindly dove into the SPINE months ago. If you put two vertical, parallel lines that run up and down the body of the vertebrae on both sides, you will notice one line is exactly vertical and parallel to the body on the left side. The one on the right is not. This is what creates that crooked illusion. Next.
"From behind" isn't perfect, either, from a proportional standpoint. When I began refining the sketches for Lumbar I-V, I realized that I left out one of the Thoracic vertebra when I was comparing spatial proportions with "From the front". This meant that I had to go back and re-render a large portion from the top and rework what I had already painted. Next.
"From the right side" was rendered entirely too small in comparison to the previous views. I caught this early, though, when I compared what I had "finished" (C. I-VII). It was a relatively painless fix, considering that I subjected myself to my own failures with the previous views. Getting the curve of the spine to look as natural and as close to my reference was the most difficult part, as well as keeping things consistent, overall, in proportional presentation.
Another very difficult thing that I had to adapt to was the very subtle differences, and gradual scaling and proportion of the vertebrae as they progressed from Cervical to Lumbar, and then to include sacrum and coccyx. You can see some of the little landmarks from vertebra-to-vertebra if you look close enough.
Assuming, however, that these little landmarks and subtle differences from vertebra-to-vertebra would make the overall rendering process easy, is a very, very big mistake.
Despite the numerous and near-fatal errors that I had made, which are still present here, I am very, very, very excited about this study. This one, that "gave" me the hardest time, is actually my favorite.
