The sketches do not really add anything, but I do hang them on the wall when I get my stylist a station of their own, just adds ambience to the room. Like Pam said, if you get a camera and use that when you start getting the option to take photo's, it does help, but even if you just take a picture of their head or even a small portion of their body, it still counts as a photo being added. Here I was trying like crazy to get the whole sim in the picture, so when I realized all you need is a small portion, then I quit trying so hard until I finally got a camera. If I did a makeover of just shoes, I would only take a picture of shoes, same with outfits or accessories and then I would name my photo. It is a fairly easy profession, but my sim is on level 10 and still only has 58% of portfolio done and only getting two photo's per week, so it is very slow going.
