I’m Peter Henley, I help publishers who are looking for simple help with drawings. Many people come to me for illustration services. I create easy and clear artwork for their stories. I help with characters and scenes step by step. My goal is to make illustrations that look nice and match the story.

I am a senior lecturer teaching integrated water resources management and leadership courses at the department of Agricultural Engineering of University of Dschang and University of Ebolowa,Cameroon as well; holding a PhD in Applied development Sciences.
