I like the tie myself. Works a lot better than I expected, to be honest.
Actually, I'm enjoying this part of the process a lot, and thinking about this has been educational for me as well. It's actually quite a common occurrence for important characters to dress a little outside the norm, but there's a balance that you have to get just right.
If I'm not too tired today, I hope to find some time to draw up some model sheets for individual characters - not so that people have to follow them rigidly, but so that they'll know which aspects of a character are important and can refer to the sheet if they're wondering how a braid or belt or whatever works. They won't be as polished as professional animation studio model sheets, but they'll be useful, I hope.
Meanwhile, here's some recent character art I put on my DeviantArt site in the past few months:
Outfits for Kel and Atra. Ignore the big-lips-and-eyes style for Kel. It was an experiment that in the end I felt didn't work out.
Kel in the dress she wears in the current story. Closer to how I actually draw her in the comic.
Another, similar one of Kel in that dress. Er, after a few scenes, I already regretted giving her that bead necklace. It's a lot of extra work to colour consistently. I'll probably leave it out or replace it with something simpler like a pin or pendant.
I toyed with a more cartoony look for the characters, but ... it's too far removed from how I normally draw to work in daily drawing. But others may like it.
Atra in her younger body in case we need it. She doesn't automatically switch outfits while the old age illusion is switched off, though. She'll still be in her old-lady clothes.
Size and body shape comparison for Younger and Older Atra. Nudity, so DeviantArt puts it behind the subscription wall.
Jake in full costume. I'll need to come up with a simplified version for the crossover, I think.
