Hi!
Sharing here the progress about the new pattern for this project:
Thanks to the Urborg, to the help in the early tests! I shared now the spritesheet here. 
Any suggestions, feel free to share with us! 🙂👍

• 1) I simplified :
  • to 4 frames, reducing load in the production,
  • removed the atk projectile; because atk #1 or #2 can be reused to this function, just changing the Fx,
  • removed Defense
  • removed transparent pixels to better performance (at least until here)

• 2) In the final result/export I think is better:
  • export each animation in a separated  png to be easier add new animations in far future.,
  • split the Fx to a separated spritesheet too,
  • delivery the aseprite to help in the adaptation for each project
  • I'm not sure about the sprite size in the empty space.... can be good keep bigger to future expansions but not so much.
     
• 3) Order of the animations.
  • idle
  • walk
  • jump (rising/falling)
  • atk 1
  • atk 2
  • death
