Delivery for @Mauricettee :) I hope you like it! I had such a hard time finding pictures... I'm really happy with the top picture (I think it fits your description perfectly). Originally, I had mirrored it below and made it look like a reflection but it looked too faint and made the cover top-heavy. I hope you're ok with the cloaked figure on the bridge. I felt like that would still work and you didn't specify anything but the twins. 

Side note: In the actual cover, the flames blend better than they do here. The mockup messed them up a bit :( Anywaysss, I hope you like it! ;)
