How do you think my 2k is?

I'm a high school rower going into my sopre year. I'm 15 years old, 6'3 and 190 pounds. I pulled a 6:54.9 on my most recent 2k. I've only done three, and I only had three hours of sleep the night before it. I'll try and do another 2k soon, but in the mean time how's my 2k?
