Playing with Stroke

I have experimented with my almost finalized panels by adding a stroke to the outside of some of the circles. I have done this to see what it adds to my design and see if it builds upon the texture or detracts from it.

PANNEL 1 - STROKE

 NO STROKE

PANNEL 2 - STROKE

 NO STROKE

PANEL 3 - STROKE

 NO STROKE

PANEL 4 -  STROKE

NO STROKE

This is probably the only panel i am sure that i prefer the stroke on rather than off, without is the background become blurry and appears almost pixelated, the stroke helps to add depth and layering to the 'chaos' emphasizing the idea of structure and noise.

I also like how it fits the idea the 'microscope' zooming in closer to the form so we start to see more detail (i.e the outline of the shapes) but at the same time the symmetrical structure starts to become lost.

I think i would like to slowly bring in a stoke across my panels to build up more of a contrast between pannel one and pannel 4.
