Cellular Biology Diagram Illustration

I’m putting together a set of study notes and need a clear, well-labeled cellular biology diagram that I can drop straight into my material. The focus is strictly biology—no grammar or literature elements—so the artwork must accurately depict cellular structures and their relationships.

What I expect
• A polished, scientifically accurate illustration ready for both print (300 dpi PDF) and digital (transparent PNG) use.
• Layered, editable source file from whichever tool you prefer—BioRender, Adobe Illustrator, Affinity Designer, or an equivalent vector package—so I can tweak colours or labels later if needed.

Acceptance criteria
• Every organelle correctly positioned, named, and spelled.
• Colour palette remains consistent and easy on the eyes when printed in greyscale.
• Final files delivered within the agreed timeline.

When you reply, please highlight the cellular-biology diagram work you’ve done before and the software you typically use. A quick sentence on how you ensure scientific accuracy will help me move fast on awarding the project.
