Thanks for the compliments and the critiques. This is the first time I have ever worked in this art style, I don't know what looks best or what my own guidelines would be (lol) so your feedback helps. Unity did not limit me in any way.
I had the lights colored near the edge because I've learned that's kind of what colored lights look like (see the neon light reference I sent above), and I chose not to add a gradient or blur between the center white and the colored edge because I thought it would better match the hand drawn simple style. (I later added gradient when making the shadows because I thought it was cool, lol)
I don't understand your point about no other object having the color line, because how could any other object have that same color line behavior when no other object is glowing? (excluding XP). Maybe I'm misunderstanding you.
The lack of outlines on the background was intentional because I was trying to have outlined objects be important, and I thought it would be distracting to have it on the background.
I didn't try out many different looks for the things in the game, so there could easily be better looking options. If I didn't get feedback like this I may never improve, so thanks again.
