I have been stacking up on books for logo design and scouting dribbble fairly intensely.
I read (and loved) David Airey’s book Logo Design Love, but what I am really looking for at this stage is a book that in lays down the principles for minimal logo design covered in this mini course.
edit: I have been studying illustration and creative drawing, but in the course, you can see that shapes are used to create space/negative space, and learning the mechanics of that technique is what I’m looking for from a book.
edit 2: Reading some of the comments/reviews from this thread as well as of the Mini course’s review thread, what I’m looking for insight specifically on is logo gridding. Apologies for not being clearer sooner.
The principles for minimal logo design are good illustration skills paired with brand identity.
The examples you gave are not logos but merely animal illustrations. It is easy to illustrate something that has a clear message, like “elephant”, or “dog”. And the clever use of negative space is simply practice. What makes this process so much harder for logos is that brands don’t have a clear identity. They have abstract values that they want to communicate to customers. If you get a grasp on that then drawing up the logo itself is the smaller task.
If you are asking about negative space specifically: look into pictures/drawings with hard shadows, find out how one single shadow can define an entire face or body. And look into illustrations/tutorial that focus on drawing negative space. This is a pure drawing/illustrating and analytical skill and has little to do with logos.
