Interesting choice in using a piccolo snare for this, as that kind of snare is usuallyt associated with reggae/ska/sublime/etc and, imo, a bit too loud in this mix, Also, the kick is too "clicky", (in mix 4) as you may want to back off on the hi-end of that bass drum. To that end, the kick and snare are drawing too much attention away from the great rhythm guitar tracks you recorded. The bass sounds good.
As to the op question, not over-compressed, but could be mixed a bit better, imo. I liked to ratio of guitar to drums better in mix 4 than in mix 5, as I would start on mix 4, reduce the "point" of the kick and snare, and start working on gluing all the instrumentation together, as if it were tracked in the same space.
