Album cover for album

I'm looking for a creative freelancer to create an album cover with an abstract theme, and incorporate some ideas I have in mind. The color palett should be slightly muted and dark. We want the cover to represent the idea of energy in an abstract way. Our music is energetic, dark, and heavy. It's neither overtly happy or sad sounding, but it tends to lean towards eliciting negative/neutral emotions (anger, sadness, anxiety). If interested, I would be more than happy to share some of our music to get a better idea.
