oh yeah sorry about not replying to that pm i'll go do that now
edit: ok this
unless you're making the thing absolutely huge this is too flat. also you might want to consider expanding out the lowest level to slope it out better and not make it so abrupt.
coloration is really nice though. try to break up the layers with bricks.
you might want to consider to switching to brick-aligned "cubes" which would be easier to work with (4x4x3bricksheight, 8x8x6bricksheight, etc). I hated having to adapt cubes to bricks to plates and probably the easiest way to solve that problem is to not even use nasty cube heights which are multiples of 10 stacked plates.
