The 1st one:Its lacking.The skeletons are looking cool dancing but you want to send a message though.The message can be sent trhough images,text,colors etc...Maybe if the skeletons was bigger and the text was better it'll look better...
The 2nd one:If you want to add an element to that sky.You can put the outline of a map in the sky of the city that scene takes place in.You can add lightning if need be....Text needs work though...
Well, what I would do is, I would change the fonts, and instead of puttin a blak bg, I would put that sky in the background instead of black, but the skeletons is tight, just add some shit to it, make it look tight....
