It sounds like you're at least average height, weight, and strength for your age. For your weight to height ratio, I'd say you could be lifting a little more. I'm 5-8, and 140lbs, and I curl 50 pounds altogether. Since you weigh considerably more than me, you should be able to outlift me more than you do (but how long you've been training makes a difference). In my opinion, it's not really impressive. People tend to get impressed when you can bench press a lot (I can't).
