Great concept and fantastic execution! Love the relationship in tones and shapes between the foreground and background, the creature really looks like it's spent it's whole life in this mountain range. Fantastic work!
You've got an awesome tints,light and shadow. I think you're weak at dynamics and expression. The connection between girl/beast is not clear at all, girl's posture is not reading - it's not dynamic enough to express some battle motion and it's bad for epic posture too,cause she's falling,obviously. Her face expression is kinda dull too - what is she trying to do? Her head is too small. I love the colors and originality, atmospheric depth is great. The beast concept is great and I love the texture. I like the girls armor design - you're really good at this. I think you should definitely review your relation to your character - cause at this kind of paintings - it is very important to convey the feelings. Another proposition - you can show more of boobs - then it will be awesome, no matter the face,pose or background hehe
