Hey there, BadliZ, welcome to OCR!
This is a nice cover of the Deus Ex title theme, here. I like the orchestral ideas you present in here, and the electro segue was neat. I'd argue that you have a better grasp on electronic sounds than orchestral ones, based on this arrangement - when using orchestral instruments it's best to really understand what each one should sound like coming from a human player (that is, knowing how instruments will strike, how they'll swell and why they do so): the process is called 'humanizing' the orchestra samples, and it takes an arrangement from decent to great, when done properly.
I liked the electronic sounds - they sound like things that Alexander Brandon would use (he's the composer for Deus Ex). Because of that it sounded pretty close to the source, overall. Not sure if that's what you'd want, but that's what it evoked, for me.
Sounds pretty good, though, thanks for sharing! I hope some of what I said will be helpful for you.
