In the first picture, it looks like rebecca and the other main character have their backs to each other holding their guns up, and there's a zombie coming at rebecca...
and in the second one, rebecca is near the front left aiming at one zombie and the other guy is in the back middle aiming at another...
but as for graphics... no you can't judge by those screenshots... but what's there to judge? It's gonna have pre-rendered backgrounds... and I heard them say it would be as good or better than RE1's... *shrugs*
