Evoking a vibe is what artists try to do. Visually enticing buyers of your product is what graphic designers do. Either use a designer or copy from the millions of expertly designed sites that already exist. You'll have to change it all anyway in a decade or two when styles and fashions change.
You're right. Rather than trying to stand out in a unique way, it's better to look like something already trusted and established. Thanks for the insight!
