The client was planning to update a website about fishing in the United Kingdom, and they needed new fish illustrations. The fish had to possess distinctive features so that anglers could identify their catches. At the same time, the illustrations had to align with the website's new style.

Some of my favourites:

Some process: a lot of photo references first, then a detailed drawing, then simplified sketch, and finally a vector image.

Unfortunately, for some reason the client still did not update their webpage design. But if they did, it could look like this.
