More squares

Is going very slowly or so I think because I am under time pressure.
Anyway I am half way down with my quilt and my mind is already racing to another 100 things to start.
I think I have to hold my horses as I still have two cardigans started , a table runner from crochet, few hundred jewellery pieces and this was the year to finish all of them.
well .... I have to get over this too...

To get back to my quilt I have below few pics 

All of them are part of the science theme which is included in my quilt
Please any comment , suggestion and opinion is very welcome and very important to me .
