Oneline illustrations Chapter 4 Animals and Nature

Oneline Illustrations Chapter 4 Animals and Nature is a set of 75 animal line art illustrations: 50 animals, from a lion and an elephant to a goldfish in its bowl, a jellyfish and a koala, plus 25 leaves. Each one is drawn by hand on a Wacom tablet in a single continuous line, so the whole animal is one irregular, living stroke. All 75 come as editable SVG, PNG and AI vectors.

Chapters 1 and 2 drew people at work and at play. This chapter turns to everything else that shares the planet with them, and it's the most graphic set in the series so far: no settings, no scenes, just the animal or the leaf on its own.

The style: one irregular line and a pale wash

The line is deep navy and it's deliberately uneven. Pressure on the pen thickens it where the hand slowed, on the curve of an elephant's back or the coil of a snake, and lets it thin to almost nothing on fast marks like whiskers, feathers and a crab's legs. You can follow the route of each drawing: the line that outlines a wolf's leg runs straight on into its chest fur, and the octopus is drawn tentacle after tentacle without a break.

Colour is used lightly. The animals get a pale butter yellow, laid as soft patches that sit off register from the line, plus a few thin yellow strokes inside the body to suggest fur, scales or a shell. The leaves swap the yellow for a fresh mint, and that mint draws the veins inside a navy outline, so each leaf reads like a quick botanical sketch rather than a filled shape.

There are no backgrounds and no shadows, just the subject centred on a square artboard. Animals are drawn with honest anatomy, not cartoon proportions: the rhino is heavy, the hummingbird is a blur of wings, the flamingo balances on one leg. Calm, light and observational, the opposite of a sticker pack.

What is inside

The 75 illustrations divide into 50 animals and 25 leaves, covering land, air and water.

• Pets: dogs, cats, a hamster, a bird in its cage and a goldfish bowl

• Wild and farm animals: lion, tiger, elephant, wolf, fox, rhino, hippo, bear, panda, koala, kangaroo, deer, moose, camel, cow, pig, sheep and a ram

• Birds: eagle, pigeon, flamingo, ostrich, hummingbird, peacock, hen, rooster and a duck

• Reptiles and aquatic life: snake, cobra, chameleon, frog, tortoise, sea turtle, dolphin, whale, shark, octopus, crab, starfish, jellyfish and a shell

• 25 leaves, including oak, fig, birch, tulip poplar, horse chestnut and fern

Who it is for

Pet brands are a natural fit. A vet clinic's booking page, a pet insurance quote flow or a dog food subscription can put a calm, recognisable animal on every step, and the light line suits a premium look better than a cartoon mascot does.

Education and kids' learning apps get a lot from the range. An animal alphabet, a habitats lesson split into land, sky and ocean, or a flashcard game all have enough subjects here to fill a full set. Nature charities, zoos and aquariums can use the aquatic group for donation pages and newsletters.

The leaves stand on their own, too. Wellness brands, plant shops, organic packaging and eco reports need botanical marks that don't look like clip art, and a single navy and mint leaf in the corner of a page does that well.

Formats and technical

All 75 illustrations are full vectors, editable and scalable without losing the hand-drawn wobble of the line.

• SVG for web, apps and Figma

• PNG with a transparent background

Pairs well with

Put people next to the animals with Oneline Illustrations Chapter 1 People At Work and Chapter 2 Activities: the hiker and the campfire scenes from Chapter 2 sit especially well beside the wolf, the deer and the leaves. This chapter is also part of the Continuous Line collection, which bundles the single-stroke packs for less than buying them one by one.
