I'm going to be very blunt and just say, ugly its very ugly, you basically achieved in turning minecraft into a dull world... the colour choice is well... horrendous, you need better colours, vibrant ones, or at least colours that are exciting to look at, take a look at one of peyton's texture pack like Bluebird for example, the sidegrass also needs a shadow and the textures need general improvements

Let me know if i need to retexture something or make it look more legit.
----Newest Update----
Once again I'll probably retexture th stone if you guys dont like it ,and the grass to.
