Design a modern logo featuring the initials 'MD' for 'Maciel Designer

Design a modern logo featuring the initials 'MD' for 'Maciel Designer.' The 'D' should be stylized to resemble a smartphone with a digital display, and the 'M' should have a sleek, modern look. Integrate elements that represent graphic design, like a pencil or a color palette, into the logo. Use a color scheme with black, white, orange, and gold accents to highlight the design. The logo should convey creativity, independence, and the ability to create high-quality designs using only a mobile device."
