You are a god. These are fantastic! I especially love the new Kraklaw front sprite (and back too). The dip down on the back of Slowpriest looks odd though.
If you do ever tackle any other front sprites by the way, the Bakurge one could use a tune up because it doesn't look up to par with the others in my opinion. Also (and anyone could easily do this) Slowpriest's front sprite's colors are a bit dull.
