#14 is interesting - it looks like you may have tried to work in the Southern Cross, which is a good idea I think. that idea of gathering under southern skies is nice. Our organiser prefers the cleaner images for reproduction, so even though your coloured blocks look great, I think he will want more white.
Would it be possible to make the emblem a little more like the Southern Cross in the Australian Flag? Again, that impact statement could maybe be bolder?
