General hand sketches assignments from Architect Studio Classes. The assignment's purpose is to observe shadows, structures, and perspectives of an object to enhance the drawing skill. The hand drawing on the right is our school Liberal Arts Building. It is a group project of four. The right-hand concern is my hand sketch. Team cooperation is very important to this project. In order to line up all the small pieces to a big sketch, we redraw the detail if the lines are not precisely lined up.
