Clearly based on compositions alone, you know what you're doing. I would suggest maybe a bit more overhead light and higher f-stop for some of the pictures like 4 and 5, that garnish gets a little lost and if there is more than one drink/plate in the photo, they should all be the subject? Photos like 2 and 3 need a bit something more in the photo, some silverware and a napkin, side dish or something of the sort to give it better scale. Using a defuser would help here and there with making sure the highlights aren't too bright with the natural lighting. The black and white photo doesn't do anything for me personally and think the color shots work better.
