When I said direct ocatves I meant direct unisons. Basically, you are approaching a unison, octave or perfect 5th in one or more voices by using the same direction of motion.
1) Direct unison #1 occurs in measure 5 from beat 4 to the 3rd beat between the violins and the viola. On the third beat the viola is on A and leaps up to the note D. At the same time on beat 3 the violins are on the note C and move up stepwise to the same note D. This is moving to a unison by "direct" or similar motion and is usually avoided.
2) Again in the 4th measure at the end of the 4th beat the viola moves up stepwise from C to D while at the same time the cello leaps from the half note F up to D. This is the case where you have approached an octave between two voices by "similar" or "direct" motion. Again, this should be avoided.
I have pointed out the problems in the Finale Attachment.
Because the ritornello repeats the problems with direct unisions and octaves also repeat. There are a couple more for me to point out but first let me know if you see and understand what I am talking about with your voice leading before I continue.
