Hi! I'm building my freelance kit, too. I def want longwear lippies, msf, brow pencils in lingering, fling, and stud and studio finish concealer (I always mess up the name but the little pot). That's just the beginning. Obvi neutral shadows (wedge, cork, saddle, etc) and shimmer highlights (nylon, expensive pink, etc) will be great too.
Thanks for sharing, love!
Hopefully what I added will be of some help, too.
