Thank you for sharing your talented work.
This redesign is amazing. I cannot promise a version of this drawing myself, since I'm focusing on other projects right now. However, if I do have some free time I'll consider drawing this.
That does sound like a possibility.
They are from the 80's series. It is more or less based of the "Chipmunks Go to the Movies" series where the characters play roles based of popular movies.
As for the role as the Wicked Witch of the West. The only Chipette that would fit that role would be Brittany - based on how she would behave as a character (quite selfish and witchy at times, but otherwise she did love her sisters).
At the time when I drew this, her character (from the 80's series) seemed to fit this role, lol.
Not yet...still working on a few other projects right now
