Awesome!!!
The shadows and Invisible Stalker would be neat (as additional creatures though, Psm's shadow fiend is already very cool plus he said these might be too different from the traditional depiction of these guys for some people's taste).
And if you ask me, there can never be enough zombies, right?
Btw, would it make sense and be of any help to already hunt for bugs in the city tileset you provided the link for or will the Q one be a completely different version?
