Well, there's always a room for improvement. Thank you though, and yes - that's the first reference pose you type in google images.
Did you have a reference for the stance ? It's a very interesting view, it seems familiar, but I couldn't find what it reminds me. I probably saw a RPG use simlilar pose for a battle sprite, for panther / lion / manticora / displacer beast. In any case, the pixelling is top notch. You have a real skill for representing animals / creatures.
