Hatch Skull with Flames

This tutorial is inspired by Hatch's bold skull illustrations. You'll build the skull from a few simple shapes, use coloured outlines instead of black, then finish it off with glowing flames bursting from the eyes.

Retro Posca Zombie

In this tutorial we’re taking inspiration from Derek Yaniger and drawing a retro zombie-style head with Posca pens. It’s a bold little character with a helmet, sharp teeth, eye bags, flies and plenty of grubby details.

Posca Zombie Head

In this tutorial, we’re drawing a zombie head with Posca pens on cardboard. This one is a good chance to play with paint pens properly, because we build the main head first, then add extra bits over the top like the tongue, worms, cap, warts and details.

Raymond Bird

This one is a slouched bird character with a scruffy look and loads of room to play with colour and texture. It’s a good one to try if you want something simple to build, then push further with outlines, wrinkles and extra feather details.

Kawaii Cloud Characters

This one is a page of simple kawaii characters all sitting in and around a cloud base. It’s a good one to try if you want to fill a page with quick characters, mix up facial expressions, and play with either Sharpie or Posca.

Fish

Same fish character, but this time it’s all about colour. We’re keeping the shape simple and pushing the finish with Posca layering, bold fills and a few rough edges turned into part of the design.

Same lobster, different approach. This time it’s all about going straight in with Posca and pushing colour, highlights, and texture without relying on pencil.

Jim Bradshaw Brainwash

This one builds on the Jim Bradshaw robot, but this time with colour. You’ll block in bold shapes first, then layer outlines, shading, and highlights to bring it to life.

FinRat

This one’s a rat character done straight in with Posca pens on cardboard. It’s all about bold colour, layering, and using flicked lines to turn a simple shape into something with a bit of attitude.
