I always prefer logo design to clint as a PDF file. But firs you should use some logo presentation mockups and try to shoe diffrent variation of your logo. Here I just creat a concept of a modern logo design for a coffee shop with a concept of coffee mug and some character for delever some massage of that logo design. always use a related mokup to present your ideo of you logo design, like the picture avobe I use a food/resturant logo mokup to present my food cafe logo to delever real feel about the brand company logodesign.
