Mrmarklin ...
If you're going to give a harsh critique you have to put your work out there too. You did very little that was constructive.
I did some searching and all I could find by Mrmarklin was a few crappy landscape shots from a few years ago. Aside from that, I saw tons of comments from him/her ripping on other members and lusting over gear. So, where's your work? Let's see if you really have the chops to give critiques, or... are you just an equipment whore?
---------------
Here's how you give a worthwhile critique (take notes)
---------------
1. Great shot. A great moment captured. Bright spot on the pants, but you already mentioned the scrim was too small. Maybe a crop would make it better? Most people, clients especially though, wouldn't notice the bright spot on the pants as being an issue.
2. Another great moment. Obviously, the DOF here is on purpose. Great focus on her. IMO, a catch light would look unnatural with the way the lighting is. Technically, the hair is too blown out and I don't like the highlight on the face but this is a lifestyle moment captured so it warrants a more relaxed critique than an actual posed or setup portrait.
3. Another great moment. You can't see their faces which makes this image more about the connection and the relationship than it is about any one person. The lines going left to right draw things in well and the extra bit on the right keeps it interesting. I'd maybe edit out her ring since it draws the eye away a bit.
4. I love this shot. It would be a great landscape shot without them and I've always loved landscape shots with people added. If I had any negative criticism it would be the darkening on the top right and the slight halo around the silo.
5. Both good shots, but a blown out chest. I'd try to recover that in the RAW file. I like the one on the right the best.
6. Love this shot. The composition with the clouds, ground and negative space around them is great.
7. Great use of framing with the branches. I like how, for the most part, the branches just frame them. Although, I'd look at editing out the two branches that intersects his neck. And, the tiny branches that extend into his legs and her butt. Probably the one just below the elbow too. And, again, I love the composition with how you included the ground. It's a compositional technique that you don't see often. The flare adds some added interest to the shot. The positioning isn't the greatest in terms of it being so low, but not much you could do there since this was obviously late in the day. Great job getting it between them though.
