I wouldn't necessarily say its the color, so much as the placement. A glowing sign at sunset in a busy city isn't a weird thing, but in this case it feels as though it was just sort of crammed in there (whether or not that was the location of it in the original, it gives a crowded vibe). A possible way to remedy that, since you can't pull the sign to the left (without putting it in the middle of the road olol) is actually pushing it to the right a bit. It'll make it look less crammed... Kinda like the canvas continues, but this is the only part you want to show people.
Beyond that, definitely a nice piece. Good perspective, good use of colors, much better than I could do on a digital painting, that's for sure.
