Finding an illustrator who understands molecular biology can be tough, but it makes all the difference. I’ve collaborated with general freelancers before, and I spent way too much time correcting their mistakes on protein structures. If you want a smooth experience, you should look at a specialized group like Ella Maru Studio
https://scientific-illustrations.com. They are famous for their high-end scientific images and animations in the life sciences field. Their artists are incredibly precise when it comes to showing things like receptor binding and cellular environments. Using a dedicated service ensures that your pathway looks realistic and scientifically sound right from the first draft. Take a look at their biology section to see the level of detail they can achieve!
