Click it, I Dare You

I've been playing too much Cookie Clicker lately... and somewhere along the line, that eye got derped, making the muzzle look bigger than it is... :I anywho, "Draw an excited pony/Draw a pony charged up" was the theme for this picture. Also, is it just me, or does the jaw line seem off as well? I'm not really sure, since I've not really drawn a pony with an open mouth much.
