Nice work! Most of these look so much more sensible than the official versions, though I have mixed feelings about Sethmon. The official turning red was always kind of weird, but your version looks a little bland. Maybe if it had kept the yellow stripes; Veemon already had the yellow mark on his head, after all.

It's also a little hard for me to fully appreciate your Sagittarimon edit, but that's probably more so because to me he not only never bore much resembalnce to the Armor of Hope, but also looked so much like a fusion of Flamedramon+Raidramon that I've always theorized that he was orginally desgined as part of a scrapped idea wherein all the new kids would reach "ultimate" level by double-armor digivolving.
