Based on this reference image. There's still a few tweaks I could make to this, but I'm already a week and a half behind and I need to move on. Fairly pleased with the result, got lots of good practise UV unwrapping and creating textures. Not quite so happy with the materials, but I think they're serviceable. Used the Grass Essentials pack to create the environment and some of the plants from the tutorial suitably autumned-up. Spent 25 hours on this.
