Thank you Yuew. I can only agree, there is an emptiness somewhere that begs to be filled, and I think it simply comes from the middle part that lacks some details. Details from top and bottom could have been spread further, just to make the transition smoother.

I'm seriously digging this whole piece. Especially this color palette. It really adds to the subtle spirit it gives off.
However, the only thing that irks me about this is the lack of detail in some parts.

Perhaps some more AA or additional details like the cracks in the pillars could tie this all together.
But aside from my nit picking, I really enjoyed this. Well done!

You're right Knightsabers, at first it was the start of a slight oscillation of the paintbrush movement, but I reworked the brush effect and this shift now looks odd. Maybe I should remove it altogether.

The single pixel left/right shift is a little dis-orienting. Otherwise, looks great!
