2D Game Character Animation

I'm seeking a skilled animator to create a 2D character animation set for a Unity game. You'll be working from a reference sprite that I'll provide, and you'll need to create new sprites and animations in the same art style.

Required Animations (5 total):
- Idle (loop)
- Run (loop)
- Jump (take-off, mid-air, landing)
- Look Up (loop, standing still)
- Look Down (loop, standing still)

Requirements:
- Moderate detail with a fair number of frames
- Frame-by-frame hand-drawn animations in the same art style as the reference sprite
- Deliver each animation as:
- PNG spritesheet 256x256 (all frames aligned, transparent background)
- Individual PNG frames (each frame as a separate PNG file, same size)
- Consistent character proportions across all animations
- Transparent background
- Short preview/gif of each animation to confirm quality

Additionally, I'm looking for the inclusion of particle effects. The character movement style is cartoonish.

Ideal Skills and Experience:
- Proficiency in 2D animation
- Experience with Unity
- Strong attention to detail
- Ability to match an existing art style
- Familiarity with creating and implementing particle effects
