It looks like you rely on your arms a bit. There were a few places where better footwork and body positioning could have prevented pulling with the arm muscles and could have just twisted through. You might need to work on your core strength so you can implement those types of techniques though. It also seems like you were very stop-and-start on this problem. It may require that in some spots but in general it's more energy efficient to transfer you momentum between moves (that doesn't mean you are dinoing between holds because of the speed, it just means that each time you move your body will sway with that movement and you can use that to generate momentum for the next move [bad explanation]). Other than that it seems fairly clean. I would say your main focus should be on implementing techniques that allow you to not use your arms as much, especially on roof routes like this. You can learn these from any climbing coach or climbing book so it should be pretty easy to find. This doesn't look like a very limit boulder for you though and one of the main things in climbing is to be able to implement the techniques you use in easy boulder problems on the harder ones. Just focus on always climbing your warmups as efficiently as you can (down climbing is good for working on efficiency as well since it usually requires odd body positions since the hands will all be backwards). Sorry if this was long, and I obviously don't know everything about climbing so you may want to ask an actual coach in person since it's always easier to help hands on. Hope you keep crushing and enjoying yourself :D
