Its coming along
and I didn't recognise my floor tile lol...
OK using the below as a rough ref:
Having the camera low frames the characters better and right now you have it low but try giving it a little tilt so the view is looking up at the foreground character and have her more in view (see below image for another rough example). Add a background light which will help pick out the shape of the characters and you also want the hero character to stand out more than the alien; the alien could almost be a silhouette, a scary shape in the background that the viewer fills in
Well hope this makes sense, and helps
