Well, I usually defer advice to the pros, but since I am the first to post, thought I'd give my take on it. I like what you've done so far...obviously, some postwork motion blur might help out a bit (but you already mentioned that). If you are trying to get the temple area to look bigger, I'd investigate a longer camera "lens". It looks like you are at medium to wide-angle. With a real camera, on wide angle, you get "building tilt". It looks like your pic. On the left, the building leans in and on the right, it also leans in. If you aren't using a short telephoto setting, I'd suggest moving the camera back and upping the focal length to 100+. See what that looks like. Since it's a "dark" kind of work, I might suggest tweaking things to make it look a bit darker...a darker sunset, perhaps. Only, you might begin to lose detail in the dark parts of the outfit(s). IF you made the whole scene a bit darker, you might be able to add some reddish-orange light from "behind" the camera to, perhaps, simulate torch light (or something similar). The guy's coat is already "flying" around pretty good. Perhaps in postwork, you could do something similar to her hair so it doesn't look "hairspray-ed" in place. One other thing...I think I know where is left leg is, but perhaps bending it a bit so it was a little more visible might make it more obvioius and show more action...perhaps bending just under her left toe and being outlined by the sky that comes through the window just under her torso. But that is just artistic idea. All-in-all, I think it looks pretty good and has potential.
