You have some great poses. On the announcement the font is a little plain. I would try at least a different one for the name to make it stand out a little more and on the second one I would crop it more, get rid of all the extra background. Focus it in more on the connection between mom and baby. The constuction one is a cute idea! The color looks a little off. The family one is precious. I'm sure they will love them.
