@Manticora, Nice modelling, but the edges look a bit too smooth, I my self at least would expect them to be choppy and jagged as if pieces got broken off and such. @poopsterspappy, Those rock debris on the floor look awesome :D I like the hero barrier idea too! @Abdullah, nice start!
@RavenTheBird looking nice! Looking for reference was a little.. awkward.. to say the least, Made a start on the wall sections to but after checking back here i think they are a little to thin, will fix them up then post them up here
