I really like #2 and #1. Others, not so as we are located in a very specific part of Australia - and the whole country image doesn't work.
Back to the ones I really do like,
a) Please include "inc.' The correct name of the organisation is "Pilbara for Purpose Inc"
b) The cumulative impact of the arrows is a 'bit' severe - perhaps you can take the edge of in some way
c) Would be good to have a go at adding a colour that lifts it a bit - looks quite dull in just brown
d) the '4' inside the circle doesn't work. Wuld you like to have another go at the number in the words?
Thanks for the talent!
Cheers
