Looks OK, but it use infrastructure cable rather than patch cable. However on te plus side the cable is probably only 2 pair rather than four pair cut back.
Infrastructure cable is solid conductor and is designed to stay in place and not be flexed too much or it will break and should go into the Krone type IDC terminals. Patch cable is multi stranded and will take plenty of movement and flexing and works well with the penetrating pins of an RJ plug.
Using multi-strand in an IDC will often result in failure and the inner conductors move and the blades do not cut the insulation or if they do contact can be iffy. Using solid conductor in an RJ plug will result in te blade sitting to one side of teh conductor and little pressure on the side and again an iffy connection can occur - or at worst no connection at all.
