beautiful work -
there's not much that i might be able to give a critique on, since its a singular piece.
but it would've perhaps been a bit more "lively" had the effect of the light from the centre/nebula been more pronounced on all else around it.
and if there were gradations of light within the nebula as well -
not something along the lines of one expansive single colored blinding projection.
still - lovely, it is.
