Fugue in E minor

So, my first time composing on four voices! Reasonably, parallels must be all over the place (as usual), but I think nothing so awful, at least, as a first try on four-voices. Here it is:

The main rule broken here is crossed voices, where a voice in a given timepoint is above a note from the higher voice from the previous timepoint. I also think the treatment of harmony is kind of weird. It likes to meander with a lot of implied dominants not resolving properly in the schema.
Also, please make sure to review other member's works here. It's great you're learning, but we all want to as well. 

Thank you @Monarcheon. Things like harmonic stuff and voice crossing may have ruined the piece, but the worst of all (I think) is the tempo. I should have raised it a bit. But anyway, done it's done and I don't know how to revert the whole fugue and change it.

As for reviewing, I often listen at what some other members do, but most times I don't really feel like having anything to add, neither to say besides a naive "It's great" to most works or a meaningless "I found this piece quite profound and programmatically expressive/catchy/interesting/emotional/harmonically pleasing/whatever..." I am no one really neither know enough about music in general to criticize accurately other people's music, it's simply not acceptable to myself trying to "teach" anyone with how little experience I have. Sorry if I'm too wrong regarding this matter and again, thank you.
