Thanks Cleo199 
Thanks marie
Actually, the beans have great aroma, and if you want to, after you have drank the coffee and eaten the cookies, you can put a bean in your mouth (not bite on it) to feel the aroma of it. The light reddish-brown foam on the surface of the coffee is crema foam, and I guess the lighting isn’t the best to make it photogenic
next time I’ll try with cappuccino or maybe a macchiato or perhaps a moccachino, I think they might be more photogenic 
Thanks Discordia 
Thanks KYBOB. Yes, after looking back at the first attempt with the single cup, it does look much more boring 
Thanks J.Vandever. That could maybe be done 
Thanks Carbohydrate. You’re right, it is quite soft. I had focused on the crema foam, and I’m thinking that maybe it would had been better to focus on the biscotti. It was taken at f/9, so maybe I need to step it down a little bit more. It was also taken with the kit lens, which definitely has some issues with off-center sharpness. Also, it was taken @ 27mm... if I would move further away, and zoom in more, I would probably get the focus better, but it was also a limitation of my setup. I haven’t got a cable nor the ST-E2 to get the flash off-camera, and I wouldn’t have been able to bounce the flash on-camera the way I wanted if I would have been further from the subject.
