New Fanfic question.

I am in the midst of making a new fanfic that will involve the Rainbooms from EG meeting their pony counterparts and vice verse.

I have a question though.

How exactly do you want the EG Rainbooms to appear in Equestria? By that I mean their looks.

1. They look like their pony counterparts but wear their clothes and have longer manes and tails tied halfway like their transformation in the movie.

2. Their human but in their transformation.

3. They look exactly like their pony counterparts except they wear clothes.

4. They have no change at all.
