Great Job!
The texture looks good and I see you have everythng under control. Once you get the hang of the process you can use things like seasonal variations to change your ground textures depending on the time of year.
Like in the screenshot below. The grass under the tree is green in Summer but, in Autum it changes to leaf littler:

A few additional hints:
You should develop and export future ground textures under your routes own developer folder. It will help avoid confusion when packaging them up for a future release.
Organize your textures into catagory folders. With the potential to have 32 Wang tiles per texture (8 tiles per season) the files will get numerous quickly.
Keep up the good work.
