Found the link to one of the earliest female minion art sites I encountered back in the noughties. Has this been posted here before? A great but now inactive livedoorblog from years ago. I think the artist was known as 'Darnarr'. Waraji was also a fan and had links to this site in his now nuked DA page. A number of other artists have done images influenced by some of Darnarr's works too I believe. Myself included.
I had lost the location nearly a decade ago as the site started to become less active. It's not in English but there must be scores of pictures here buried in the sea of art work. You'd have to scroll through each month or filter by the story tags, but I recall some of my favourite works were sourced from here. Unfortunately I can't find my original collection so I'm trawling though again. I think most if not all images are intact so intend to save any in case we lose them to the ether.
愚者のイラスト箱:October 2008 - livedoor Blog(ブログ)
This is from the Oct 21 2008 entry. I recall an amazing sequence involving these characters but it must be spread out over months rather than one after the other.
EDIT: I can link images such as the one above but can't upload or post any other way. Just seen a wonderful zako example in the latest Star Wars comic. Once the image issue is resolved I will be posting it.
