Nah, I like the original.
Out of curiosity, why? The original was painted by a professional, and I'm still pretty new at this, so it isn't very surprising.
It's hard to tell their skill from the picture, since theirs is zoomed out a lot, but is it just the way the chest looks? Or is it the colour selection? Or something else?
I honestly like your style better than the professionals I've seen. I'd say the tone of your miniatures is generally cartoonish, and I prefer that.
