i really love this! i love everything from the colors to the pose to the general idea as a whole. your take on the harpy is really interesting (and the color scheme reminds me of Sylveon haha)

the one thing that i would change would probably be the hair. it seems very flat and lacking of detail. if you go back over it to create strands of hair, it would fix it up. other than the hair, there's not much i would personally change. i really love this. keep up the good work :)
