1) Nice scene. A lot of the sky is blown out (and er111a's edit made that worse which is why I prefer this one). I'm thinking a polarizing filter may help?
2) The red draws my attention to the chair, which isn't particularly interesting in itself. Table cloth looks over exposed. Perhaps a little more space and an off-centre position for the table would have been more pleasing?
3) The light from the windows is causing you problems, and more light is needed on the subject (the flowers). A piece of white card would have helped.
Thank you for the edit and feedback. I was having problems with the first one. It was a very hot day and the sky was already hazy and almost blown out. I can't remember if i used a cp or not. It also drives me a little crazy because i hadn't noticed the tag of her shirt til i got home.
