It a unique look.
What I find that helps with bring together skins for modules is to look online/google about a certain type of design that matches your vision. then you can use those clip art/images as a grounding to allow a better flow from one skin to another. This will also aid in creating the atmosphere for your planet wither it is a more colorful vegas feel of a dark gothic horror,..it all comes about keeping a mood/tone within the planet and the images/clip art of the style you like will help keep it more balanced. Most of the time a skin just need to be tweaked and slid over to another spot where it might work nicer with another skin verse the one next to it originally.
Just food for thought
