I do have value shifts on the buildings where they should be in shadow but probably not dark enough. I'm not sure if it's because of the lighting of the photo, you know it could be the reflection of the flash that they look lighter. When I look at the painting I can see the distinct differences. I'm terrible with taking pictures and use a very cheap camera. But then it's true that I have a hesitation holding me back when putting in shadows because I know I can always make something darker but making something lighter is not easy. So I'm really undecided of whether or not I want to fix it. I might just leave it and try the picture again with darker values on the buildings shadows in the next one. I enjoyed doing this picture and would enjoy doing it again, maybe this time with a blue sky as in day time with some rougher water like waves against the rocks.
Thanks for your critique Chanda, I value your opinion and advice. And thanks for the compliment, it means a lot to me.
