That's ok, not in the mood for a zombie survival sim. Now that I think of it, I've never really been into the zombie genre, aside from maybe L4D (which is hardly a "traditional" zombie game) or Walking Dead (which, again, is less about zombies than story and characters).
For me at least, the outline is too thick - and too even - to work as a shadow, not least because there are actual shadows in the scene that suggest the light is coming from somewhere else. One other thing: the Wilma/Betty hybrid in the earlier pic seems to have more depth, mostly due to the slightly lit edges, and this is enhanced by the grain, which makes the character look less flat. Will this one get a similar effect?
