It's not supposed to be creepy. I thought the light blue was a nice color to bring out the line drawing I made and have it appear as more of an anotomical drawing. Good for anyone who ever had the urge to become a paleontologist.
Structural items can be very interesting. The fact that this animal is standing upright gives it a more human feel that makes the viewer relate to it. So now it's not just a mere structural scientific item. With the dangling bone wings this becomes a weird angel-looking creature that is missing its flesh. It almost becomes demonic. It's quite scary.
If you are going the route of interesting structural items that are of interest to paleontologists, try to pick something that is:
A) Not as humanoid.
B) Doesn't have a religious aspect to it (i.e. no wings).
