Looking good! A few power labels yet to be changed over.
Now, if this is going to become a PCB and not just an exercise, it’ll need a power header and associated components (including bypass caps by the op amp chips); they’re left off Sam’s stripboard layouts for whatever reason. There’s a whole topic about that: Typical module power circuit. For Kosmo or Eurorack formats, but if you’re doing something else it’s only the header itself that might be different.
