Well, I can only speak from experience and what I know. I've been personally lifting for about 5 years. I started at around 12-15% BF (130lbs) and only got more aesthetic from there. I'm actually exactly the same height as you and am currently 175 sub 10% body fat. So at the very least, that is possible. You have a LONG way to go before you hit your natty max and I think you will be surprised at how good you can look. Of course, at our height, getting to 200 with a six pack will be near impossible. Just keep going and you will make it brah!
