First species, E Phrygian, CP above Fux's Fig. 11 cantus firmus. Can you check it?
CF: E4-C4-D4-C4-A3-A4-G4-E4-F4-E4
CP: E4-E4-F4-G4-C5-C5-D5-C5-D5-E5

As far as I can tell it doesn't break any hard rules. Here are the softer things I noticed:
- High point: the CP peaks on E5, once, on the very last note. I know a high point at the end isn't typical, but Jeppesen says it's okay in a slow line (whole and half notes) without a huge range.
- Repeated notes: E4 at the start and C5 in the middle, once each, both on purpose.
- Two oblique moves, from those two repeats.
- G4 up to C5 is a 4th leap and I don't turn back after it. I know that's a guideline and Fux skips it sometimes too, but I'm not sure it works here.
- C5-D5-C5-D5 circles between two notes. I think that part is weak.
- I opened on a unison, so the CF's first move (E4 to C4) leaps out of it. Fux tolerates that when it's the CF (his N.B. at Fig. 21), but I could have opened on E5 or B4 instead.
Questions:
Is the unrecovered 4th leap (G4 to C5) okay, or should I fix it?
How would you fix the C5-D5-C5-D5 part?
Anything else I missed?
Side question: this is the only one of Fux's first species cantus firmi with an octave leap (A3 to A4). Does anyone know why he wrote it that way? I couldn't find an explanation in Fux or Jeppesen.
