I like the second screen some less, because the green color feels a little out of place in my opinion.
the overal color is pretty warm (red, yellow, brown)
but the green is more towards blue, which makes it a colder color.
but still, these screens look awesome!

I wonder... how have you done those water/lava effects?
it seems like it has a vertex shader to animate it, am I right?
