This is the earliest sketching stage I recorded in the creation process but its life had long began at conception with the first stroke of the pencil on paper -- which is usually an arc. I couldn't give a better answer to why I often begin with an arc than a rethoric 'why the heck not'.
The drawing takes on a life of its own at the rhythm and tempo I set for it. I can take it in any direction I feel fit. That's the beauty of creating designs, there are no rules - you tune in into your emotions and go -- stay tuned in and your idea blossoms!  
Since this, as its title suggests, is an abstract design, there is really no such thing as completeness to it. I can stop it wherever it feels like it's finished -- like at this stage. But wait, how about that tentacle I feel protruding from over there!
This is the stage I wind it up and determine that the abstraction can handle conversation with its observer on its own. 
I introduce colors and textures digitally but in many cases I start by recreating the image in vector format so I can take advantage of my smooth curvaceous lines.
It's a jungle out there when it comes to color combinations and textures for abstract concepts. Several of my designs make fascinating surface patterns but sometimes I remove some elements of the design to make more interesting motifs fit for certain repeats.
It's still different strokes for different folks, to me this can make excellent wallpaper and textiles for interior applications.
In this concept as wallpaper , the design can be muted to subleties of different degrees to be less engaging; it's all a matter of taste. 
In this application as an upholstery fabric, the accent armchair demands that you pay some attention to it!
Thank you so much for watching my project.
