How To Draw Manga,

The base should be plain. Even the variations in light that i've put are'nt neccesary, but they gift nice effect , they can be also be added latter on.

the ground grass is short, monotonous ( look same ) and the staw all face  the same way, if we can dont use custom brush, cuz that is cheating :D,  just makes small curves carefree move with you hand slowly , mouse user might have problems trough.

add more stroke where you thinkis fits ,remember that the grass is'nt supose to grow symmytrically, Darken the fields that stand out to much, i added a stronger light in the back to get some deep in the pictures.

if the grass is'nt rece, crntly moved or something there will be longer, wilder stands that sprawls all over the place , create new layer and draw thicker, longer straws mostly in the front.

add some ' wild straws' on the back too. but keep them smaller and less obvious then the one closer up, you can put with a slightly different color if you feel like it.

finally you just add a few random stands wherever you think theres is too few, As a final touch edit the shadow and color as you please.
