Losses do tend to have better review value, but I'll look through for a few things to point out:
7: A bit passive. There might be situations where you would get more from this move (like if the middle was very critical or if there were weak groups nearby or something), but in this case, it's better to hane aggressively at F3.

Something like this is standard, and works well with your other stones.
9: Good choice. This blocks your opponent's top corner's primary direction of play, and also extends well from your corner stone.
11: This is also quite good. This is bigger than your opponent's last play. Not only is the area you're playing in wider, the stones on both side are high (on the fourth line) so this region has more potential than the left side. This could also be on the fourth line if you wanted.
15: Since you can reasonably push into the bottom-left corner, I would be tempted to. However, that could become a heavy group, so perhaps it would be better to jump to D6/E7, threatening to reduce in the left also. That said, the move you played is also big. Since you're approaching a fairly strong corner, a two-space extension is stronger and safer.

The move you made is an elephant jump. It presents the weak spot shown above. Elephant jumps can potentially be great moves in specific situations (jumping to a critical point, spoiling eyespace, and so on), however, it's better not to make one unless you have a specific plan. You're making tons of points up top (especially once you block the top right 3-3 invasion), so taking the knight's move at 'a' instead would do a lot to help you wall the left side off. Notably, white gets around to taking this point at 64.
All in all, good game. You had a strong opening and got a lot of kills. Your opponent played a lot of passive moves, so it's harder to point out mistakes of yours. For the moment, keep an eye on that monkey jump, remember the 3-4 hane at 7, and try to repeat the things I complimented in similar situations. I look forwards to seeing your next game!
