continue my thumbnails sketching in process and i have done half and half with pencils and photoshop so i can keep my photoshop in practice and also did quick sketching for ideas. But don't really know what means good so still keep on sketching for experimental.
and i sketched the boxes below with photoshop, keep practicing my skills with different brushes. Some of them i zoomed really close and some of them i sketched as normal size. After i finished every single box, i found the bottom right group of boxes were connected with the black. It is interesting while that is not i expected to create new form of structure from mountains and trees.
