"BLOCK-CHAINED" - A work in progress

Lately, I've been working on this piece entitled "Block-Chained", it's 50 x 70 cm, acrylic on paper. It's still very rough and unfinished. While painting, I've been experimenting with altering the colors digitally, the results are very helpful to guide me through other palette options . Some of the results are quite surprising and present some really beautiful color variations.

-Original in progress, with unaltered colors

Below are four examples, that were treated digitally in terms of hues and saturations.

I'll post the finished painting later this week.
