These are really nice. I like the cleanliness of the first one (it is an interesting combination of images, as well) and the build-up of layers in the second one. Is your journal a sketchbook with blank pages or is it an old book?
I'm a design student too, except on the other side of the US. The little details are great and the actual book jacket designs are really nice. Is there anywhere we can go to see more of the inside design?
