Hey! I don't know if this is intentional, but the perspective makes her look like she's 30 feet tall. If you want some constructive criticism, I'd say the perspective could use some work. The house is almost isometric and partially hidden, but you can roughly find the vanishing point using the roof, and then if you use that vanishing point to draw lines to Sylvanas, you'll find that she's much taller than the house. The perspective on the house and the trail also don't really match.

I'm no expert on perspective myself, but I'd recommend checking out some perspective tutorials, because something is definitely off with the perspective here (assuming she's around her regular height). Aside from that everything else looks awesome! If you improve the perspective, you'll definitely have a masterpiece on your hands ;D
