None of it is final, it's pretty busy and will be turned down.
Did you already turn it down since posting the image? It looks pretty reasonable to me. If not, may be a question of which screen it's viewed on, since I'm seeing it on my phone at this moment. But either way, I've always liked the vibrant flowering meadows of Dwarf Fortress much better than the unnatural and homogeneous modern lawns which tend to inexplicably turn up in a lot of fantasy and historical games.
Maybe it looks too much worse when tiled? It's not like I checked that.
It would be great to see the grass in big picture. I love the initial screenshots for how clean and focused the graphic is - the grass is grass,
I can focus on important things, rather than seeing mishmash of different tiles which represent the grass at different stages of growth (so basically, meaningless thing to me).
To say "grass is grass" in this case is erroneous. Grass has never been a simple homogeneous backdrop unless it's specifically engineered as such. Furthermore, length does matter of you're using the grass to graze livestock, which as far as I can think of is the only case where it matters at all, in a practical sense.
Actually, I think the wildflower blooms in particular are too understated. I ASCII and most tilesets, when spring comes, the vibrant flowers capture the beauty of the same phenomenon in real life. Since this graphical change is meant to be an upgrade, it would be a shame to lose that with the comparatively sparse and dull flowers shown in these examples. Right now, those show only a dirty smattering of color over a great dominant field of the same late summer green that is shown for growth at other times of year.
