Animals & Nature Line Icons
While it started as an experiment playing with various sizes and amount of details per icon, it grew into a full-blown set of icons which could be suitable for your next web project, especially if it involves responsiveness in mind.
The line weight always stays the same, 2px, which gives them a super-consistent look. Of course, since they are crafted as vector shapes, size is not a limiting factor. Billboard is what comes to my mind.
