I am using Watercolor and alcohol for this semi abstract arts.
It is a view card which I made recently where I am using black and white background and a bit splashing of isopropyle alcohol . Although the effects of it is not showing much on the picture the way I took the picture of it is less light as not using extra head light or something.
Anyway, my semi abstract Bubbles are colorful and attached to each other, kind a like small molecule or tiny cellular . Some are popped up represented with tiny white stars around those adhesive bubbles. The shiny reflection inside of each bubble represents like door to tiny magical wonderland world or some parallel universe.
