When it comes to retail wall decorating mistakes, overcrowding the space or using art that doesn’t reflect your brand are top issues. Generic prints may look polished but fail to make a memorable impression. Placement matters too, artwork should guide the customer journey, not clutter or distract. Sizing is another pitfall; pieces that are too small get lost, and ones too large can overwhelm. Lighting is often overlooked, yet crucial to showcasing the art effectively. Avoid these mistakes by working with a professional mural artist who understands spatial composition, branding, and customer engagement.
