man i fucking love this concept, this is really nice! and i cant quite deicide if i like your old one better haha. the armour looks great, i must say tho that the dress really distracts from the rest of the image. i think it has a bit to much going on. try downloading some tutorials on painting people/fabric. you might also need to identify a good light source! shadows make everything look amazing xD and yeah! i know its a top down lighting scheme haha also try giving it a focal length, right now your backrgound has a lot of detail, but really you want all your attention to be centred on Zelda, the background comes second to her, general you find with shots like this is that the details in the back are blurred where the details in front are really crisp and sharp.
ps: please take all of what i have said with a pinch of salt :)
