for example when I jump my wings bob up and down (which i think looks ugly) or the animation speeds up when i run faster (which is also not good looking) which especially when you combine those 2 things looks horrendous. so i would suggest making these things adjustable (Max Animation Speed, Min Animation Speed, Jump Physics , etc.)
Also the loop on the wings (Feather Wings Pink) is broken they just loop in a random position and teleport
