Dragon scales and skin

After getting feedback from Linh, I changed up a number of the scales, making the ones along the wings not quite as pronounced, and removing a number of the smaller scales on the body, so that the head can stand out more in contrast to the rest. I also added in more skin folds, thinking that since the hide of this dragon is thicker and has heavier scales, it would probably have to be looser to allow movement. Took a look at the T-Rex from Jurassic Park in particular for reference. Also added some surface texture and bumpiness to the scales.
