We, the rock band Voltraid from Ingolstadt, need a design for our new album entitled "Rock'n'roll Religion". The cover should have a certain erotic appeal and be somewhat provocative. The scene to be depicted is a lady wearing lingerie, sitting with her legs apart on a Marshall guitar amplifier. Her arms are tied behind her with chains to a kind of cross made of guitar necks. It is important that they are Gibson guitar necks with the characteristic "open book" headstock. I'm not quite sure what the background would look better. Either a kind of cathedral with gothic decorated arches, or a background made entirely of black Marshall speakers. Unfortunately, I'm very bad at drawing, but I've sketched it out very roughly (see attachment). In terms of style, it should look something like the cover of the Slash album Apocalytic Love (see attachment).
