you'd be free to modify designs as you like. I must still be credited and linked to for the original design no matter how much they change though. You free to modify just about anything, from changing some colors or markings, to changing the species or adding things like wings, scars, robotic features and so on. Even using a myo to turn them into a closed species, so long as its ok with the said closed species, i don't mind and there's no need to ask permission from me.
If you've purchased a design off me you own it, which includes the ability to change and redesign them as much as you desire. ^^
