composition

 - Started doing studies of single fish, rather than piles of multiple so that it breaks up the book - allows some space within all the fish drawings.
- Did it first without a background and then scanned in a second version with a bit of shadow. But unsure of which to use for a final illustration, as the first one looks like the fish are just floating in the middle of the page which is a big contrast to the compositions of my other fish drawings. The second looks more like a finished piece as it has a bit more depth to it. 

I want the illustration above to be paired with this one on a double page spread, and I quite like the composition of this with the wide expanse of negative space surrounding it. 
The two might be paired better together if they have a similar sense of floating on the page.
