Not only do the wings not look "cheapy", they look shockingly authentic! Since your ability to create a very convincing look for them, I'm going to go out on a limb and point out a couple of things for future creations of this type. As someone who firmly believes that I actually know firsthand what a succubus' wings look like, there are two details that do stand out here. One is that just as you don't normally see a bird perched or walking with its wings partly extended, a succubus's wings are normally tucked in to her back. This being said, for artistic purposes, it's often not possible to depict them this way since they would all but vanish from an angle such as this, being in line behind her body. Still worth noting though, for when the camera angle permits, at rest, they would appear something like a pair of dorsal fins on a fish. Of further note, the way she carries her wings are often a reflection of mood. Think of how a dog carries its tail. In this image, her posture and facial expression appear to exude confidence, but the droop to her wings implies timidity or submissiveness. Please don't think I am implying any criticism by these comments. Quite the opposite, in fact, I only mention them because you rendered those wings with so much effectiveness that such details are actually noticeable. In most Morrigan images, the wings look sufficiently unnatural or even cartoonish that nuances like this would completely slip by. kudos on a job VERY well done here.
