You're pretty free to do whatever you want, since my characters can be interchangeably swapped between each drawing (thanks to their androgynous looks! >3<).
Guy or girl, tied or messy hair...blegh.
The only thing consistent between them is their blue eyes, black hair, and fair-pale skin, but...
...suppose you wanted tan lines? <---The girl then.
Heck, you can even draw them both doing something together (just not romantic, because...welp, I hope 2nd and 3rd leaves the right impressions, because they might be related in more than one way), if you so feel like it! :3
