Sketch:

I've always adored this image from the Japanese laser disks for StarS. I've been wanting to draw it for YEARS, and a some time back I had a chance but I just wasn't confident enough in my skills to get it to look right with how closely they're interacting so I opted for a different image from (I think) some trading card thing. On a whim I've had it tucked away in my files again for a little while and finally decided to take a crack at it. And, albeit not romantic in nature, it still just happens to work for Valentines Day! (or more, "Galentines" in this case)
As for the sketch, I didn't have to make any major changes or fixes, but the ribbon on Chibi Moon's bow were traced in because I just wasn't happy with how my attempt came out as well as Saturn's.... right(? uh... the one behind Chibi Moon) hand to help compensate for the opacity I added to the bow and sleeves. The rest.... was just a LOT of polishing with help from older works.
