Wow… Amazing pics mate 
I’ll second @PsychoTeapot re LightRoom.
I’d never even heard of the RAW format before I got my Mavic.
Then @RaRaRasputin introduced me to the wonders of post editing with his LR video at Mavic Pro Lightroom Stills
I’ve not looked back since 
(I bought a cheapy/old LR on ebay too)
