Your man looks fine except for the skin tone and his pose. Make his skin a little darker so he appears more rugged/manly. Loosening his arms and neck up a little. There's a lot of flack going on about the V3 male not looking masculine enough but that's a bunch of bull hockey. Not all men have the square look. His tanktop would stand out a little more if you add a bump map. The one thing I notice about your composition is that you have your characters really dressed down but you seem to have your enviroment a bit more "classed up." There appears to be some tension between your characters. Perhaps its a money issue. Try adding some props to make the room a bit more cluttered. The red couch doesn't seem to fit. Perhaps something such as a print or a bit more neutral would fit better. Consider your lighting. Do you really need such a light wall texture? Consider a light blue or tan. Also the painting is nice if these characters are rich or exist in some fantasy world. But if you are trying to depict real life consider putting pictures of your characters on the wall as a family portrait. Also a lamp and an inn table might be nice. You also have a great big space on the couch which is empty. Perhaps the man is upset because there is clutter on the couch or his seat is being occupied by the family dog. Your lady looks very miffed so I wouldn't change anything about her except perhaps having her wear a pink print rather than solids. These are just my suggestions. I don't want you to think I'm being condescending or that anything major detracts from your picture. You have an excellent start and I am glad to be given the opportunity to chime in on a picture I know will turn out. Good Luck :) PapaBlueMarlin
