Need advice on what to do...

so i'm finally breaking down and making myself the 3 rainmakers in masterpiece size. my question is with them being so bright should i panel line them and if so in black or a darker version of the paint once i choose it. i'm torn because without panel lining i think they will just look kinda blah, but black panel lining i'm thinking will detract from the look they have. any thoughts/suggestions would be greatly appreciated.
