bits from today and bits from yesterday

this one was drawing a large square then drawing a smaller square inside then rubbing out the larger square. 

it's too light and not interesting enough - too much field

I like this 

but there to still two ideas in it and I want one 

like the way the lines of the curved ones don't quite meet - this is another work 

still not sure - don't like the circles maybe too distracting from the lines

i can't see this image - but think it is the black one - i like it - but it's too field and not enough diagram 

basically this is made by sticker a white piece of paper down then going over with pen 

i was interested in the bit when the pen went off the edge of the paper 

this one i prefer especially for the little corner at the bottom of right does so much so simply 

need to do more with lines around the white paper 

levels 

this one i really like 

but isn't a diagram so not sure about it 

lines look like something else but not sure what at the moment
