Clean Lineweight. I also like how certain drawings have the lines intentionally over-extended like Paul had shown. Very simple color scheme of dark greys and one red highlight. Compositional combination of foam models and sketches is a nice perspective from the real world.

Geometric trucks with a train feel. I enjoy the ability to bring very small, rough sketches on the side to life with a quick brush of marker.

Simple and clean lines, with distinct line weights supplemented through shading.

Strong composition of chairs, arranged in a golden ratio type of arc. The yellow bar also intrigues me as while it looks useless, I think it makes the images pop out more.

A strong progression of drawing leading from geometry to rendering.

Quite concise drawings. Simple concepts that have the clear base structures (ellipses) still visible on the page.

Unique views using perspective shapes. Simple, clean, and still professional.
