Random Thumbnail Sketches

Tried for a while to make some quick black and white landscape composition after a long time. Basic target was following some standard rules of composition and adjusting value on it. Attempted to append some special brushes as well! Do not hesitate asking me if you want my customized brushes ;) and feel free to leave your thoughts.
Here are gifs to show a glance of the procedure I followed step by step. Thanks for watching!
