I've been making this for the last week and wanted to see what people make of it, see if there's anything to improve upon.

Very nice, do you use Photoshop? My only complaint maybe that the top color doesn't really fit too well, maybe something bluer.
Also is there a specific order to to the Jedi being lined up? I always look for any hidden meanings in pictures even when there aren't

Yes, I use photoshop. You mean the background? I wasn't too keen on the background looking like that. I could maybe have them set up from their ranking, Luke on the right and Yoda on the left.

I like it, but Luke doesn't fit in the picture in my opinion.

@erictuong Would it be due to him being the odd one out since he's in the originals and the others are part of the prequels?

Not bad at all, I like it. May be you could use another background pic instead of this grey, (too much contrast to my taste.) Why not keeping the black ground with the reflect and replacing the two grey spaces by simply...space with stars, or also with a planet to give volume and perspective ?

Kind of simplistic but nice one. I Like it.
I'm not a pro, but may be some more contrast adjustmens? IMHO, Qui-Gon Jinn could be better in a row with other Jedi.
And, If you based it upon an old canon - also known as SW Legends now - then, maybe, there should be a Corruscant cityscape on background to make it more lively?
