Here's my custom
TFA Season 3 Sari Sumdac:

I started off with a 3.75"
Star Wars: The Clone Wars Padme Amidala figure, then sculpted on the extra details with modeling putty. This was my first time working with the stuff, which was... interesting, especially at such a small size!

I then painted her using Formula P3 acrylics. It took a little mixing to get the right shades, but I'm quite pleased with the results. The colours don't really come across in the photos thanks to the lousy lighting, so you'll just have to take me at my word, I guess!
For reference, here she is with Leader-class Bulkhead and Deluxe-class Bumblebee.

Considering how inconsistent the relative sizes of characters are on
TFA, I feel pretty good about her scale. She's probably a touch too big, but what are you going to do?
The key and Allspark are from the Unicron.com Accessory Set #6. I know, technically by the time Sari looks like this the Allspark is long since shattered and the key is drained of power, so just chalk it up to creative license.
In any case, you can see the full gallery
here. Let me know what you think!
