The scale length looks right. They just look like they're strings made for standard Fender style inline-4 tuners, not 2+2 tuners where the D and G pegs are much further away from the nut on the Fender style.
- For the E, A, and D strings you're fine because the further down the post the strings go, the sharper the break angle over the nut, the better it is. Like everyone else says, usually cut to 3.5" past the post.
- The G string i might consider pulling and trimming a bit so it's not doubled back over itself. But if it stays in tune and the intonation is good and you don't have any weird dead spots or anything, you can probably just leave it and trim your next set of strings. Up to you.
- Having the non-silk part of the string wrapping around the tuning peg is usually only a serious problem if you're using Flats or Tapes. Flats or Tapes will start splitting or separating from the core if you wind the non-silk section. Most Roundwound are fine having the non-silk wrapping around. It's probably fine, unless you notice the winding splitting from the core at the peg, and then it's not. But don't worry about that unless it happens, and then you'll know you need different strings anyway.
- If you have a Fender Style inline 4 with the 1/2" thick tuning posts, you can get away without clipping most brands of strings. And it's actually beneficial not to for a few reasons. But for the 3/8" tuners and 2+2 layouts, definitely clip to 3" or 4" past the post.
