Nice idea and animation. It's convincing fire.
Maybe try again with less colours? Having so many colours for such a small asset, while totally fine by modern game asset standards, goes against the 'spirit' of pixel art, IMO.
Avoiding brushes with translucency and soft edges will help manage the colour count :D
Thank u for commend, this my first work in pixel-art animation. I training every day and up my skill in drow :)
And i'am has started work on new pixel-art animation!
