Preliminary sketches new painting on the way

Just starting work towards a new animal painting and here is a series of thumbnail sketches in biro to work out the composition. First pic above, quite like the arrangement of the group of 4 cows but the one on the right isn't adding too much.
Sketch 2, below, is looking more balanced but perhaps a bit crowded and the middle trio are all on a straight line.

No 3 below, slightly better arrangement

No 4, simplify things by reducing the herd to 3 cows and add some landscape in the background

sketch 5, prefer the staggered positions /distances here

Number 6: Think this is it, just 3 cows some landscape visible thro the gaps and I like the arrangement of the bovines.
