Some constructive criticism if I may, I feel like the "Mega Moonlight Mania" doesn't fit the composition all too well. The "Azakaela" works, it looks like a neon sign in the background, but the title looks a little out of place. I think the color doesn't really help it and the font kind of reminds me of pirates, which sort of makes it stand out as not part of the scene. I do however like how it sort of looks like it's floating into the scene, which does tie it into the whole cover.
But again, I really like the atmosphere, it feels like a calm and chilly night in a futuristic city. It makes me wonder what business Moon Girl is up to. She kind of looks like a ghost to me and it seems like she's in a hurry, which both helps bring across the mania. Nice work :)
