cool cool add an glow effect if you want to go teh easy way its something you can pick like itll say GLOW EFFECT or something
and having all three is okay but they all mean different things
pick one color that signifies something so people see it and think what kind of person is that why did they choose just that one ( one being red yellow or green )
put some mystery to your work make your audience want to come back and know more of your mind and skills...
