Ah, we see a little bit of Ram here ;)
If ever you have trouble differentiating the twins, here's another hint: the one who curves their body more would be Richard (not that Ramona didn't like to show her forms here and there, but if the two are side by side, Richard probably wins).
On an unrelated note, I do like Allan's sweater I gave him. I was never too comfortable with drawing clothes and making them up for my characters (some artists are amazing at that, hot dang), I don't think being uncomfortable myself with choosing my own clothes help :D
That's a fun thing to note with all artists: you can see how their own lifestyles, visions, body, their own personal life, influences their art. Like, someone who have a certain type of nose might draw many of their characters with that same nose OR! If the artist isn't comfortable with their own nose then NONE of their characters have a similar nose as them. You know what I mean? Me being the opposite of a fashion queen clearly makes it harder for me to invent a fashionable new outfit for my characters. I also tend to forget giving characters jewels of any sort because of my own lack of it.
That reminds me, I remember very early Roomie fanarts showing Roomie with make-up and jewels galore and it felt very bizarre to me. Clearly we didn't see Roomie the same way!
