I think both are good but extremely repetitive. The older one is more pleasing to the eyes than the newer one, because the grass in the newer one makes too much detail where detail isn't necessary at all. Because you use the same clusters over and over it looks to me more like wall paper than grass.
By mixing some of the new clusters in your old texture, you'll get a touch more variety, but keep the general soft and pleasing appeareance of the old one.
Apart from that I ask myself if it's a good possibility to have texture flowers and object flowers in the same tileset. I had the same problem, but I don't found an answer.
I think that you should alter the bush leaves in the same way like you altered you tree textures. Also making the darkest part (lower half) a bit darker could improve the 3d-ness a bit.
But all in all it looks already great, and if you want to hear my opinion: work on and make more stuff, it's always possible to (ex)change things later. You have a great style there and I wonder how the charakters and the other stuff will look like. If it's for a "real" game it's more important to get lots of stuff done, instead of perfectionizing all in the first round. You'll always find something which you can improve later.
