Ya know ... and this may be the power of suggestion at work, as I did read the above comment ...
Curious of you could achieve some additional depth by having the central portion of your abstract more clearly delineated?
Viewing your "Aurora 2" piece, it seems to be that it would. As I do detect that facet somewhat more on that one.
I could see some nice interplay with your arcs/ribbons of colour becoming a more prominent element as a result too.
Annnd ... since I am on a roll here with suggestions, thoughts (just kidding, of course) ... the areas to the left and right of the darker bands that appear just left and right of center?
More shadowing there could accomplish that added dimensionality I am referring to.
Just some thoughts.
Kind of getting a vibe of curtains of flame here ... I like it too. Don't know if it was your artistic intention to somehow incorporate the letter 'V', but it would appear that you have. Either way, intentional or not ... it works well with your title.
