How to avoid this next time?

Everything network related on the picture I did on my own including pulling the cable that is inside the wall and installing the wall plate. Anything I could have done differently to make this better?

If I was more skilled and had courage to crimp the cable to the exact length it would look slightly better than what it is now but it would still look messy. Is there even better way? Did I already failed by using that wall plate? Would angular cable endings help here?
