I suggest going through the monster girl encyclopedia books and doing some monster girls that you find "inspiring"

I have a few suggestions, I just don't know if they are any good.
First idea 3 more Pokemon. Mew, Sneasel and Meowscarada would be my idea.
You've done dragons before and I don't know if the Spyro game like Skylander tells you anything. But Spyro, Cynder or Skylander characters like Whirlwind or Flashwing.
And I think you had made a few Digimon. I could think of something like Gazimon, Meicoomon or Biyomon

I have one last idea. You made the mushroom beast from Genshin Impact.
You could try making the Melusine as a base? into a sexy adult from
These were a few ideas, but I don't know if they would be that helpful^^

I know I'd like to see a Zekrom base, although I'd also would back the Mew idea as well.

And I do want to back the dragon idea as well. Although personally, I prefer Spyro's design from the original games (and the Legend games) over the Skylander designs.
