Much better than the previous batch. I like where you're going with this.
I think the grain is a bit too extreme now but it's not unrealistic. It would depend on the film stock as some film pictures are this grainy. The ones where I think don't work for me are the 5th ( the trees) and the 8th (city shot). Both of these I think the grain is too much. The one of the trees as well looks like there's more detail in the leaves than that amount of grain would show.
