Don't know how the two are similar at all besides the masks. This album cover is fucking horrendous. It's a bland white wall with two girls looking awkward in masks. The font is also ugly. It looks like they spent a total of fifteen minutes on it. TDAG's artwork actually looks like it has meaning to it.
Technically, you could argue that Lydia spent more time on theirs since it looks like they had the art made, TDAG was taken from a collection. Not that it matters, since TDAG's art is really, really good.
