Approval Process Snake Chart Design

I need a clean, visually engaging snake-style chart that maps the entire approval process from start to finish. The chart must clearly show three sequential steps—Initial review, Stakeholder meetings, and Final approval—laid out along a winding, continuous path so viewers can grasp the flow at a glance relating to Injection moulding processes and products, attached a copy of an illustration/sample.

Visual elements are essential. Please weave in:
• Distinct icons that instantly identify each step.
• Consistent color coding to separate stages and reinforce progress.
• Milestone markers that punctuate the path and highlight key decision points.

The final artwork should balance clarity with impact and be delivered in an editable vector or layered file (AI, Figma, or PSD) plus a high-resolution PDF/PNG ready for presentation. also need as editable version to change and alter depending on the project.
