Not great. It looks like I've just been doodling. Which isn't necessarily a bad thing. I quite want there to be a sketchiness/uncertainty to the whole thing which more reflects science as it is done in real life rather than how it appears in text books.
However, when I got down to actually continuing on with the painting it really didn't need all these extra elements so I decided on the electron arrangement to appear behind and half hidden by the elements. It works well at this scale but in the back of my mind I keep hold of the final size of 4x6 feet. Will I need more elements at that scale? Pfft - don't know yet.
So where from here? Originally I wasn't going to put in all the elements but just have boxes. As things are progressing I think they need to go in. I need to work out a way of emphasizing some and pushing others into the shadows without everything getting too regimented.
