    Is the connection between TIP127-2/7k5 and D9/D10/zener intentional? If so, I would run the trace so it doesn't look like an accidental cross (4-way connection).

    Check your trace-to-pad clearances; there are a few places, like the 8V input connector pins or the anode of D4 where they look a bit close

    I was taught to avoid 90-degree bends in traces, and to use two 45-degree ones instead.

    Make the polarity indicators for the electrolytics a bit larger and visible when the part is loaded.
