Coming off of that last one is a much more traditional, but very beautiful depiction whose main features are a double set of fluffy angel wings and some very nice, pixelly lineart. It manages to be both clean and impressively detailed, which is typical of really good, large-scale pixel art. ^_^
Angelic wings are actually pretty common in Gardevoir fanart. It makes sense - they're somewhat otherworldly creatures, sworn guardians with the frail and featureless physique of symbolic angels. I think. That was a legitimate sentence, right? In any case, it's a pretty motif when used appropriately, and that is certainly the case here!
