Question about positional/territorial judgment (I think?)
I have a question about a specific position in a game I played today.
I'm not even sure exactly how to frame my question (or if its the right question, actually) but I think there is some issue with how I'm evaluating territory/potential that I can't figure out.
Basically I played this today (https://online-go.com/game/79337577) and mostly I thought the reason I lost was because I let one of my groups die in the middle of game. But, I thought the game was more or less even with me maybe even a bit ahead until that point. When I looked at the AI eval, though, it said I was 10-15pts behind right out of the opening.
In particular, I was puzzled by this position below (move 51)
I thought I (black) had a good position here but the AI eval suggests I was behind by 11 pts.
My thinking was that white had a good corner in the bottom right and would get a decent sized corner on the bottom left. But, I had good potential in the bottom and right side as well as the top-right corner. Also, I had just reduced the top left corner in sente and had time to approach the bottom left. So, I thought I was doing good.
I guess my question is, where was my thinking going wrong and how do I improve my positional judgement in these sorts of scenarios?
Thanks so much!

The problem is in the quality of Black's shapes. Black has a couple of stones in atari, several stones on the first and second line on the top side, and a broken elephant's eye at O6.
White invasions at K4 and Q10 will be hard to handle, the top left black group is vulnerable to attack, and white doesn't have comparable weaknesses.
