Thank you very much!
I already thought nobody would ever reply xD
I can understand your words, but I must admit, I do have a bit of a problem understanding the meaning fully.
Could you make some notes and examples directly on my picture? that would help me out tremendously.
About the problem with the central pillars stairways- I didn't modify them in any way, it's a photo of the hanging monastry in china,
and it looks indeed just like that :
guess I'll have to study the photos a bit more to figure a solution for the problem, or just rethink the concept of the middle pillar
And the hint with the black and white layer, I'll make sure to keep that in mind for my future works.
again, thank you very much for your awesome critique
