Exploration with Zentangles

Today is Skull appreciate day, click on the image above for more details.

I was experimenting with using black outline and fill the details with limited palette of colours. These are not intended for atcs even though I used a blank atc for canvas size. They are still zentangles in way because there has to repeating pattern of one form or another and not necessary in monochrome. I feel by adding colour it make the image 'pop'. I intend to use these rainbow zentangles for artistamps and printed on larger size not the pixel size. The first 3 blocks are simple because I had a lack of decent sleep. In some case it's not always worth the effort as it prohibits creativity. 4th block I was inspired by looking at a plank of wood and how the stripes resembles sound waves, stretching and becoming narrow. The last block I took 3/4 felt pens created lines until a pattern formed. I find 3 zentangles can be created at time or becomes tedious. There is no time limit to creativity. At the moment I'll still working on RZ028 Blade Liger the process is slow, check out my crafty blog for much of the work is completed so far. I still would create some paper embroidery atcs. Sometimes there are 'hollow period' or hobbies don't provide any sustenance any more. I find going out for a walk helps because whenever I'm on the bus, lots of ideas pop in my head.
