Fantastic, really like the grass, sincere thanks for sharing the process!
Most grass when you inspect it, grows from a clump of thick brown roots, and it's great to see the colour variation(brown to dark green, with brown reed type blades ) in the final texture.
Your grass has an authentic feel(well it would based on a photo reference! but still the type of grass selected was great), most people don't realise that grass isn't just a uniform collection of green blades.
Great to see how much attention & work went it to create the texture it show BTW...I'm off to find me some good looking grass samples!!
