An idea I had was that Melody ( https://satinminions.com/search.php?tags=Character-Melody ) should be more of an apprentice than a servant, and these two would be her next project - and prove to be a bit of a handful.

>They look rather androgynous. Are they male? Or, immature female?

They have the ability to switch.

>Hard to tell, but they seem to have their horns hooked together.

They aren't but with the way they're shaped, they should be careful.

I use an old Intuos 3 tablet, which is better than a lot of new tablets because of the button cluster. It has several buttons grouped together that can be differentiated by feel along with a scroll strip. The trend with newer tablets is to have a row of buttons down the side which is not as quick or easy to press.

I used Krita this image, and most of the recent images. It is free and open source. It's good for drawing but if I need to do a complex layout with masking, lots of text, or a super smooth gradient, I'll go back to Photoshop CS 9. CS9 is old but it does not require a subscription or internet activation.

For a few of the really smooth vector animations, I used a program that I wrote myself.

Done. Also attached this image to the end of the comic.
