Ashtyn, this is not the type image I shoot so take my thoughts for what they are, general in nature. The first image is rather busy, although it does possibly speak to whom the couple is. Figuring the props are all something included for a reason personal to them, what I might do is to selectively sharpen the people and dog. I might also bump their exposure a tad. I might then slightly blurr the background and add a very slight vignette.
In the second, I like the pose but it is a pitty about the branch acrossed them. A tough clone job for sure.
In the last image, for me....it beggs for a B&W conversion.
Hope I at least sparked some ideas.
