I know I did one piece including Nina. I've done sketches of Rachel, but I've never published or finished them. I usually just center in on Gary. There isn't much Alphas Fanart out there to begin with anyway.
Well it was from last year. As the new season starts on Monday, I might start drawing more Alphas art and if a character appeals to me I might draw them. Its more of a spur of the moment thing when I draw.
