Spine emoji

I’m looking for a clean, minimalist mascot illustration for a chiropractic clinic website chatbot.

The character will represent a friendly, approachable “spine” and will be used as the chatbot icon (small size on website), so it needs to be simple, clear, and highly recognisable.

This is not a cartoonish or childish style — the brand is premium, professional, and reassuring.
Concept

Abstract spine-shaped character
Smooth, curved “swoosh” style form (not anatomically detailed)
Big friendly eyes
Open smiling mouth (as if speaking)
Expressive but still clean and minimal

Should feel:

Reassuring
Professional
Friendly
Trustworthy
Style Requirements
Minimalist / modern
Clean vector style (similar to tech/health startups)
Soft curves, no harsh edges
No heavy outlines
No clutter or excessive detail

Should work at very small sizes (chat bubble icon)
Colour
Primary version: white character (for use on coloured background)

Also provide:
Dark/black version
Optional subtle accent version (if appropriate)

Deliverables
SVG (vector, fully scalable)
PNG (transparent background)
Favicon/chat icon size version
Source file (AI or Figma)

Variations (important)
Please include 3 expression versions:
Neutral friendly smile (default)
Talking (open mouth slightly wider)
Slightly empathetic/concerned (subtle variation)

Usage Context
Website chatbot bubble

Needs to feel inviting and encourage interaction
Must look good at small scale on mobile

References / Direction
Style inspiration:
Simple tech mascots
Modern healthcare branding
Clean SaaS illustration style

Avoid:
Cartoon mascots (too playful/childish)
Realistic anatomical spines
Overly detailed or complex designs

Important
This is for a premium chiropractic clinic, so the design must feel:
Calm
Professional
High-quality
Not gimmicky

What I Need From You
2–3 initial concepts
Revisions to refine the chosen direction
Final polished vector files

Bonus (if you offer it)
Subtle animation-ready version (optional)
