Are there any adopted characters of yours that you have tweaked in any way? Any that you have kept 100% of the design?
For the most part, no. I pretty much keep my characters the same, unless there's some aspect to their design that I don't like or just doesn't seem to fit the character's design at all. XD I can't think of any characters who I've really done that to, other than my male tiger, Akull Kasai. He was created by someone else and when I adopted him, I didn't like what seemed to be random raindrop markings. I thought he looked much better without them than he did with them. XD
Also, when I bred a digital version of my real life rabbit, Belle, with someone else's pixel rabbit, we ended up with Springer as one of the babies, he didn't have any color to his eyes in the pixels he was created in (the breeding was done by someone else so...yeah ^^;) so I decided I wanted him to have eyes the color of milk chocolate, since his mom had brown eyes anyway, I felt he should too. XD For a time, when I did him in Oekaki color-ins, he somehow wound up with half his legs being white and then I realized...wait. That's not part of his design.

Hm...who else? XD Oh! Mavik Emerson, the red panda I got from...was it Raven Feather? I don't remember. XD I'm going to have to go through my messages and figure that out. XD Anyway, I plan on removing some of his items because he has way too many and they just clutter his design. I don't know...to me, a character's design should be fluid. Everything works together in harmony to create one nice character. Mavik came to me with items seemingly everywhere. No offense meant to his creator, but he didn't need all the ribbons, necklaces, and so on. XD Eventually, I'm going to need to find someone with a red panda lineart to color him in and put the items that I want him to keep on him. ^^;
And that's all I can think of at the moment. XD
