In looking at the completed drawing here I can see that I need to add a little violet in the top aqua. Which, because the drawing is done with markers, will be very easy to do!
With the addition of some violet on the top of this drawing the viewer's eye is led around the center of interest which is the 'box-like' structure in the top third of the drawing. In looking once again at the drawing on the screen I'm going to make one more change.
A totally different look to it! This view is quite dramatic - I don't know, yet, which way will be right side up.
I've included here the original drawing. I loved it when I finished it but now find it flat and dull. The latest iteration I find bright and lively.
