Hey so i have done a landscape , i was trying to push myself alittle with having some water in the scen but also mix low and highpoly flowers, and I also modeled the butterfly for some extra effect.
This took me about a week and thou I see the limitations in the hair particles for making gras , I was almost happy with this, but next time i will try andrew price grass essentials
but for now here is the butterfly effect 
btw some feedback would be highly appreciated
