Cool! I like a lot of things about this :D
First off, the design for the creature is awesome. You made it look very heavy and beastlike, and definitely very threatening. The pose of the girl jumping away is also very good as it not only fits the situation but is very accurate anatomically. The outfit you chose is pretty cool for a wild barbarian type character, and all together the composition of the two subjects just looks like an awesome fight scene. The creature clinging on to the cliff is really well drawn too, and the sun in the background with the red sky makes everything much more dramatic. Great work, keep it up!!
