If you’re in the mood for bold and bright nail art that’s fun and fresh, it’s hard to beat the work of New York City-based nail art pro and Instagram personality Tommy Dorfman. If you’re looking for a tutorial with a simple build-it tip, it’s just as easy to follow his steps. For a retro-inspired look, nailing her lines and pins perfectly adds a perfect accent to a freshly done manicure.

About a year ago, while at a Barnes & Noble, Dorfman spotted an abundance of colorful nail art pens. She had never seen these before, so she purchased one and took to Instagram with her first tutorial. “I put up a picture of some of the more vibrant and colorful pen designs, and I immediately had hundreds of followers,” she told POPSUGAR. Dorfman has kept up her Instagram following and has doubled the number of follower likes every month on average since.

A graduate of the fashion design program at Parsons School of Design, Dorfman also has a degree in fashion merchandising, which she put to use while creating these intricate nail art designs. Dorfman created her masterpiece tips without a computer or any help from the internet, using her passion for art to complete her work. She told POPSUGAR, “Since the photographs are so limited, I play around a lot with my color palettes to visually build the look out.”

With each photo she posted, she tried adding more color and it took her hours to find the perfect mix of texture, saturation, and stripes. Dorfman explained, “I also try to keep it fun and funky, but with simplicity, since I think it looks best when it’s minimal.” All of her nail art designs can be found here.
