Would you say that this musical phrase sounds too similar to this other musical phrase?

Two years ago, I played a piece of music written by Bach (well, an arrangement).

Recently, I composed a piece of music which was inspired by that Bach piece, but I thought it sounded reasonably different.

I did a side-by-side comparison between the piece I composed, and one of the musical phrases created by Bach. I picked the two most similar sections, and make it so that both of the tempi/key signatures were the same.

Here is the audio result. The first phrase is mine, the second is Bach’s.

I think that they sound reasonably different, especially the D♮ in my version (musical source code). I also think that they will sound more different as I add harmony. However, I want confirmation from a third party. What do you think?
