Needs a little work. Has potential, but there are a few attention to detail errors and possible bugs with this livery. For starters, there are two prominent blue panels on the underside of the left wing, the fairing of the Trimmable Horizontal Stabilizer and the MLG wheel fairings are both white (should be blue), and the logo on the tail appears to be a bit off, being slightly lower and smaller than the real aircraft. I have attached photos of the real N708EV from the web for reference in addition to my screenshots.
Additionally, the ATC callsign is incorrect. This aircraft is operated by SkyWest Airlines on behalf of Delta Air Lines, and the correct callsign for the "atc_id" field in the .cfg file would be "SkyWest". This is easy enough for the end user to correct, but still something that detracts from the quality of this livery.
I want to end this comment off by saying I do appreciate your work and hope that you will find the time to update this livery so that it can be its best. :)

hey! Any chance this will be updated for the V2 update? thanks

Hey! Is it possible to update this registration? Delta is taking on some CRJ 550! :D
N708EV Is one of the current CRJ 550 flying with delta based in Salt Lake city.
