What is so bad about this picture. . .

[Rose Guardian]

I made this using a template from Manga Studio Ex for the figure. NO I did not draw directly on the template I had it on another screen and put it in this pose. The last person who saw this really hurt my feelings by saying that his anatomy was at fault. Since I used a temnplate and am very good at drawing what I can see what is so bad about this cover? How can the anatomy be at fault if I used a template and was able to put it in that pose and am very good at drawing what I see?
