Thanks so much, guys. I really appreciate all the kind words.
With regards to the GS - yup, first try. I did a little fimo sculpting as a kid, but nothing this intricate or tiny. It feels like cheating a little, though, because the particular items I chose to sculpt were really easy.
I didn't know any of the useful tips for sculpting with GS I've read up on since, so my method was kind of ridiculous. I used a ziplock freezer bag as a work surface so nothing would stick, and a bit of water to help that along/smooth out my fingerprints. A dull craft knife was my tool of choice. Basically the two big books were just thin sheets of GS flattened under my thumb and then cut into rectangles - thicker, slightly larger ones for the covers, and around three thinner, smaller ones for the pages. For the folded book, I stacked the pages, folded them in half, chopped a bit off the back and folded the cover around them. Then a thin line near the spine to mark the binding.
For the flat book, I stacked the three pages, warped them a bit to look curved open and pressed a line down the middle, then stuck them to the cover. Scrolls were pretty much the same, just rolled into tubes and then one corner massaged a tiny bit to curl outwards.
Painting really made all the difference - lining between the pages to give them depth and such.
JackMann - I'll try that, thank you. I was pretty happy with the highlights on raised sections (compared to my previous work, not compared to some of the amazing versions of Damien I've seen online and goggled at), but the back of that coat, man... I had no idea what I was doing.
