If you're trying to cut down on words then rather than reading through to edit try looking at each individual sentence in isolation. For each sentence read through omitting different words. If it still makes sense take out the superfluous words.
It sounds tedious but it's a very quick and tidy way of tightening up your writing.
I've done an example below:

Hi there all! So I am doing the EPQ, artefact precisely, and its a short movie called "The Artificial Man". My topic is the social and financial aspect on those that suffer limb loss, ultimately going with prosthetics and/or bionics. I took inspiration from the Alton Towers incident, where a girl had lost her leg, in the end getting a rather expensive prosthetic. Im currently reworking my 1000 word essay, but its still at 3000 and im not sure what is needed, what isnt, my college hasnt given any guidence. Any tips/help???
