I haven't done this much in the past, but what I'm doing more and more now in my sketchbook is filling a page with just one big sketch. I guess it's odd to me because I'm used to working really small.
One of the main inspirations for this was Andrew Mar @Andrewkmar on Instagram. I'm absolutely in love with his work and I'm hoping to get a tattoo design tattooed on me sometime soon ;^)))
