Toph- A degital inkpaint test

I'm trying to simulate the feeling of chinese inkpainting. but it's more difficult than i expect.
It take me a long time to get the texture right. and i still haven't figure out how to control the moisture of the bursh.
For the out come, some detail feels ok, but overall don't please me.
I'd like to know if you like this style or not, any comments please let me know.
and feel free to take it for any practicing or coloring. I probably won't be able to finish it with coloring.
