First off, welcome. You have a handsome face. You look good with what you have now and if you ask me, enjoy what you have while you still can but if the urge to go short becomes unbearable, go for it.
Like the other members had mentioned, it's not that bad. There is some recession, but (IMO) you still have some decent coverage.
I decided to crop mine when a light breeze would undo all my handy styling work. That made me the most uncomfortable and I knew i needed a change. In my opinion, you don't look like you're at that place so you could probably hold onto it for longer.
But i'll have to agree with the others as well: it's your hair so the decision is yours, if you can feel comfortable with your current hair then maybe hold off, if you do decide to cut close then maybe go with a short crop (like a 1 or a 2) and then shave it off all together ... i sincerely think you could pull off a cropped or shaved look.
Thanks for the feedback. I cut my sides and back down to a 2 and left the top the same as it was. I guess I'll delay being sly for a little longer. Because of the comments here, I'll feel more comfortable becoming sly when that time comes.
