TrinityInRainbows, welcome to the thread from a fellow Seattle-ite! I actually created a post a while ago showing the posing capabilities of Dear Mine MSD body. You can find it here. Most of your questions are answered in that post
About the bust joint. I generally prefer well engineered bust joints vs. waist joints, but it's all a matter of preference. I have both Irene and Priscilla, and the bust joints are easy to manipulate on both girls (their bodies are identical, except feet - Irene has human feet and Priscilla has more animal-like feet).
When you ask if her make-up "clashes" easily, what exactly do you mean? I have 5 Dear Mine dolls at home, and the face-ups on each of them has held up beautifully over time.
Please ask any other questions you may have!
chibi-kagu, Nelli is gorgeous! I really love that wig on her
