Again, if you're going for Bach, no. It also doesn't follow a lot of the Baroque voice leading rules, but if it's not Baroque then don't worry about it.
You could argue it's a diatonic fugue, but a standard tonal fugue would have your answer actually in the key of the dominant (Fâ) (occasionally subdominant i.e. Bach Tocatta/Fugue), instead of a transposed version with the intervals changed. The fact that your third entrance is the same as the second is also a little strange.
