Not too shabby for less than a year of training. Things that stand out... You are aggressive, but I feel like there's a waste of energy. Also you are going halfway with a lot of things. Like the sweeps you were working a few times you only went halfway, with the armlock you were trying you were only going halfway (not the last one, that one was nice). A lot of that is attributed to lack of hip movement. You kept a closed guard for most of the match, which is hard to attack from in no gi, especially when you aren't shifting your hips around or trying to really create something. Another thing that gets me is the mount. There was already a thread about how to hold a mount, you were grapevining the legs, which a lot of guys like to do and such, but to me it's a waste of time. You can have just as much control and put your opponent in danger by working towards a higher mount and threatening his arms. A low mount with grapevines, is a very passive mount, you can't much work anything from there.
I'm probably being a bit hard on you, but honestly you did a really good job. Excellent sweep there, then great transition from the back to the armbar. Keep training hard and you'll only get better.
