For a friend of a friend's shrimp import business:
Actually the version I submitted was just two colors, no white highlights. Rather subdued. My pal added bright colors and removed some of my dramatic shadows (based on photo reference, incidentally.) If you're curious, that version is at swimminglastnight.com.
Here's the original sketch I did. I like the vinegar in this lettering, but it was difficult to ink by hand without wavering, so I found a font. Maybe I should have braved it and just left the imperfections.
