Teresa Jenellen – Designer

I am an illustrator specialising in watercolour with a love of colourful characters and gloom.


I work from home in Machynlleth the Ancient Capital of Wales, right next to the oldest graveyard in town, in a crumbling house with my black cat, black chickens, heavy metal husband... and a ginger pom named Foxy!

I am a genuine bookworm and history nerd. I love getting my teeth into a good story and bringing the characters to life and I'm always happy to go the extra mile to get every detail right. I have worked on all sorts of projects from book covers and full story illustrations to theatre and festival posters. I have experienced easy breezy several months notice covers and 'any chance you can' super fast turnarounds. No job is too big or too small and every challenge is approached with equal enthusiasm. I am easygoing, upbeat and I work well with others.

Teresa is the best. She is delightful to work with and her art is beautiful. She delivered to me just the cover I was looking for, and was very responsive to any changes I asked to see. I look forward to working with her for my entire series, and maybe more beyond that. She is a treasure, and I am very happy to have connected with her. In short, she rocks!

She was both responsive and had a keen eye for how to fix things and make certain ideas come across even greater on the page. Her style and colouring is breathtaking, and you can tell from the end result that she really enjoys ...

Teresa continues to have the artistic genius that keeps me coming back for more. Her style is so gorgeous that readers pick up my book because of the cover. When they ask about the cover art, they are always amazed by Teresa's portfolio. Not only is Teresa a brilliant artist, but she is also an incredible human being whom I look forward to collaborating with on my next novel.

Working with Teresa was an absolute pleasure! Upon seeing her portfolio, I knew she was the right artist to design the cover for my book; what she delivered went beyond my expectations. She was able to translate my ideas into a cohesive, coherent concept and translate it beautifully onto the page. Beyond her artistic talents, communication was easy and clear, and pricing was very fair. I would ...
