Create 2D Parallax backgrounds with crystalized theming

I'm creating a 2D game which is crystal themed, however I need parallax 2D "crystalized" environments. For example, the game will have 5 levels. Each one has a type of environment. Level 1 is set on a forest during the night, level 2 is set on a desert during the day, level 3 is set on a frozen landscape during the day, level 4 is set on a cloud on the sky during the night (clouds are tangible since they are crystal and all that) and finally level 5 is set on a cave with a mix of the colors of the past 4 levels (1, 2, 3 and 4). With that said, I'm imagining all those scenarios with every element "crystalized", every single one, from the ground to the threes, even the clouds, moon and sun. The attached images may be useful for reference, just picture all of the elements on the images as crystalized and their colors mantained, however they have that kind of reflective look, also if possible, add glowing effects to borders of the elements. Remember, every element is a crystalized glowing version of themselves. There is a pdf of the main characters of the game, to help adapt the look of the "crystalized" versions of the environments.
