I truly love your art style and these skeletons have depth and character, they could even be used as player characters. As far as the art style, and quality 5/5. The main problem I have is printing them out. They are formated huge, if you would print them without modification they would be 166mm each, I had to experiment with reduction of size to get them near 30mm tabletop size. Printing at 18% seems to be close to 28 or 30mm range. So once you print at 18% you could fit another 8 on the page (waste of paper real estate). As far as printing and the trial and error I had to go through 1/5. The lack of back art, black outline, and lack of any color options doesn't help the situation.
All in all I am excited to see more of your art and minis, please keep 'em coming! Once the page size and number of minis per page is fixed, and you add some back art and black outlines, this product will be formidable.
I will change my rating if this product is improved.
