But are the pieces wholly original, or were you given the soprano line?

 

Just focusing on the first one, and assuming we leave the soprano intact in m.1-4, I see that the 3rd beat of m.1 you have a 5th over 2 non-primary notes of the key, a bit weak IMO. Remember, 5ths and 5ths sounds hollow, 6ths and 3rds are fuller. This isn't a rule at all, but those hollow 5ths sound better if one or both notes are important in the scale, i.e. D, G and A.

In m.2 you double the C#, the leading tone, and it sounds very weak. Duplicating the leading tone is a big no-no in common-practise harmony, unless it's something fortuitous as in contrary motion. I'd harmonize the C# with a 3rd or a 6th.

M.2 the E and B form a 4th, i.e. a 2nd inversion chord. That should be resolved, and it sounds weak. the D in the bass is a dissonance which you don't resolve (if you had B-C# D, the D could be a passing tone).

the E minor outlined in m.3 is fine, but the F#-C# diad weak, because the mediant chord is weak.

Measure 4 is fine, but maybe I'd switch the C# and the A , because a chord in root position in a stronger beat is... stronger.

M 5-7 are the same assuming you do the invertible counterpoint thingy.

In m.8, I'd end the piece in a perfect cadence, i.e. the bass doing an A-D motion. Here you must avoid parallel 8ves, but direct 8ves and 5ths from contrary motion are allowed in perfect cadences.

I've done like Mike and toyed with your material a bit, and let's see if that gives you ideas. First is your melody with my bassline, and then inverted. Then I made a different continuation to your theme to give it more momentum.

My version is built in period form with 4+4 measures. Also, each 4-measure half is a sentence, i.e. I have your idea in m.1, I vary it in m.2, and then I create a phrase that's 2x longer and that develops the same idea. Also notice how the melody goes higher and higher to have mini-climaxes. Melodies that have mountain or valley form are especially effective.

I might be breaking some baroque counterpoint rules bc I used a more 19th century approach tho
