Sci-Fi Elements

Since my film is sci-fi I have a lot of power to play around with stuff, such as flying cars and laser guns.

However what level of sci-fi do I go is the question?

The Star Wars Saga is full 100% sci-fi therefore I don't think it would be wise to go full sci-fi because this would mean a lot of props and other CGI elements to use.  I mean this would be awesome however I don't have the crew or the time to create something like this.

The next film which has less Sci-fi but still loads of CGI is Elysium

I loved this film for the balance between props and CGI animation which became flawless, I think it would be possible to create something which contains this level of CGI, however the props will suffer as I have a low budget and have no team in which to create it however looking into this shows I don't have to go full blown CGI stuff with little props but just make the background believable.

FInal one to look at is blade runner which is set in the not to distant future?

 This will be useful for my Intro scene of the city being panned down!
But being able to reference real world and manipulate it into the sci fi world would be the best move for my film.

Another thing to note is video copilots VFX sci-fi tutorial which I'm following, sadly they don't have the full assets for you, instaed they have only given me the footage of the guy shooting, which I prefer because it makes the footage become mine as I add the VFX for the blast coming out of the gun.

I believe this will be awesome for my Sci FI guns in the film.
