3rd time lucky? - attached it.
Got it.
Why it is not a fugue:
1) It lacks a recapitulation section.
2) The 2nd voice enter before the completion of the first and is unneccesarily altered.
3) Ditto the third with respect to the 2nd
4) There is no development of the third voice (and precious little of the other two)
5) The First F (in the bass) shoud be sharp.
6) It would be more correct for the 3rd subject to enter on the tonic (and to restate the subject exactly).
7) The free counterpoint of the 1st voice should be in invertable counterpoint, and should be at the octave or the 15th.
EDIT: 8 ) [Damn emoticon thingies!!] One note is not sufficient to constitute a countersubject to voice 2 (or to be free counterpoint, or to tell which was intended)
Basically, it's not possible to write a 3 voice fugue in three bars.
I'm thirsty.
