Write now this is more a less a personal project of mine, though I certainly welcome anyone reading this to try it out for themselves. Here are some simple rules and guidelines for the challenge:
1. Though it's called the 90 Day Monster Girl Challenge, I'm setting the completion date to one year, because doing this for 3 months straight is probably too much to ask for anyone who isn't an insanely talented artist! It doesn't matter when you start the challenge, but that you complete the challenge within twelve months after you started [for example, if you start the challenge right now, you will have until the end of May 2017 to complete the challenge].
2. All creations must be done for the challenge, though you are free to use characters or designs you've already created, so long as they fit into the presented categories, and are actually created within the time the challenge is started.
3. Any art medium is welcome, be it traditional, digital, 2d, 3d, or even literary.
4. Since it is a longer challenge, artists are free to spend more than one day working on an individual monster girl. For the sake of avoiding spending too much time on a single subject, I recommend planning to complete a subject by three days, otherwise people could end up not having enough time to complete the challenge in a year, as hard as it is to believe. It's alright if it takes a little longer than three days, so long as you work to make sure you can complete the challenge as a whole by the end of the year.
5. This goes without saying, but do your best. It doesn't matter how it compares to anyone else's work, so long as it's clearly a completed project within the limits of your current skills.
6. If what you come up with is NSFW, please use a spoiler and post a warning if there's any potentially objectional material in it. Please nothing too extreme.
7. It doesn't matter what order you do the list in, just try and make sure you keep track of which monster girls you've already done.
8. MOST IMPORTANT RULE: Try to have fun and be creative!

Spoiler: show
Like I said, this is primarily a challenge to myself, to get my creative gears going and actually do some monster girl designs from beginning to end, but nothing would make me happier than to see others competing in this challenge as well! I'll make sure to include a link to my gallery on deviantArt and any other sites were I post my artwork, once I have them established.
