If the horse is 'framing up' then that is fantastic. Unless, you aren't an english/equitation/hunter/jumper person (haha, I used a lot of slashes xD) . That pose in the picture, although weak, is known as 'being in a frame' and the horse is encourage to propel from the hind-end, to move into your hand and thus be 'on the bit'. This is a coveted level of training by most english (dressage, HJ or equitation) riders. I'm not sure about western though.
Either way, its not a fault - its fantastic if it is in fact a frame, and you ride english. If western, well, thats beyond my scope of knowledge. Best of luck!
