I was exploring a hand drawn illustration style for storytelling, trying out different styles. This, more simplistic yet sketchy style was my favourite. Done in AI.

Since it was a storytelling for a techcompany with a lot of contractors and builders as customers I also played with the idea of Blueprints, and made a strip of sketches in a blue print colour style... 

Mixing story telling parts with elements (in the execution part) from the service it self - yet maintaining the same visual style. Same illustrations also worked well on a white background and softly coloured with "water paint". But that didn't feel techy enough for the purpose.
