Poster for bushfire benfit event

So i decided to try out affinity designer for a poster fora benefit event my wife & I are organising for those affected by the recent australian bushfire crisis. This is the result. i think i'll switch to Affinity over Illustrator where possible, certainly for my freelance & personal work. This is quite heavily cropped but the full poster is available on the event page
