Thanks so much, guys!!! I'm learning a lot from this already. I still have some editing and refining to do on my shop, so I'll let you know when I update that. In terms of color variations, I actually have a couple different ones that look fairly different from what I've already posted, some of it from just variations in color mixing (trying slightly different things and it not quite turning out how I expected) and a couple where I was trying a little more shading to see if I could make them a bit more realistic. I'll post a picture of that soon, I think.
