I like this very much. You've done a seamless job integrating the background elements, & the roses are a nice touch. Your extraction of the tiger is the best I've ever seen, right down to the fur on his edges. The orientations of model & tiger are perfect for your intention as the poses look very natural - no sign of any awkwardness trying to fit them together. The additions you've made to her hair are also very natural & very skillfully done. The few traces of colour work well, especially the tiger's eyes.
My only difficulty is with the lighting. The main shadowing on both girl & tiger imply a light source from the left, so there is a inconsistency in the highlight on her left hand, which should actually be shadowed. It is so light it draws my eye away from the main focus of the scene.
Congratulations - it's a well-thought out & technically very assured piece.
