The initials "AF" need to be identifiable as such. I realize to make a logo cool it needs some styling, but I will be using just the AF in some instances (Facebook avatar for example) and I want it to be recognizable as those letters.
Think "Lamborghini" more than "Rolls Royce." I want it to convey speed, aggressive performance, sleekness. I think in the AF portion angling the letters will help capture this. Also, if you want an idea for color, since I did say green (and it doesn't HAVE to be green, I've seen some nice black/white/grey fades) here is a picture of a Porsche with the green tone/highlights I like: https://bit.ly/2QAlHtP
