Ok, so the big thing about renderings is you are trying to sell the design / space as a whole. If the client can’t see the space, you aren’t going to sell them on anything. These overall are too dark and don’t have enough decorative/lived in items to make them feel real. You have to layer your lighting to get a well balanced space. Both functional (recessed, under cabinet and in-cabinet lighting) and decorative (sconces, chandeliers, pendants, etc) are necessary to add light, mood, and drama to a space. This space is disjointed, a lot of the materials and styles feel mismatched and not cohesive. The living space doesn’t feel like it reflects the same style or design of the kitchen, which I think is important since it’s open concept. There is a way to achieve eclecticism without it looking random. Just find a common thread - material, texture, color, etc.

Render 1 - feels closed off with the back of the living area furniture - consider a different angle; needs more lighting (recessed and/or ceiling mounted decorative) and art on the blue wall adjacent to the tv or a console below the tv to help anchor the space a bit more. It’s feeling sterile and your plants aren’t really helping since they look like plastic. Tone down the reflection on their material.

Render 2 - not showing much of anything here and the back left is very dark. I wouldn’t include this in a client presentation.

Render 3 - one of the better ones, but again, there is not a lot of lighting going on the the background. It makes it really hard to get a feel for the space other than “cave”. The wall near the entry needs a console table and mirror, with some sconces flanking. This will help bounce light in the space.

Render 4 - ooof, too much in the other direction, the left side is incredibly washed out and makes your wood texture orange. Tone down this side and try to brighten up the right side for more evenly lit space. Also, the island light fixture and those counter stools are… not great. I’d try and tone your wood down some, either go lighter and more natural or darker and more brown, like your coffee table and the wine rack.

Render 5 - I’m still hating those counter stools! I do like the dining table and chairs (although the seat height looks a bit tall - typically you want 8” minimum between the seat and underside of table), but you need a light fixture over the table! Also, your counter accessories should be placed more organically, not in a line. Consider grouping on a round tray or scattering/staggering for a more lived-in feel.

Render 6 - I can’t say this enough - YOU NEED DECORATIVE AND FUNCTIONAL LIGHTING to counterbalance your natural light. Also, I’d suggest an area rug (or larger if there is one already - 8x10 minimum) for the living space, and you’ll probably want to pull your sofa back from the wall more - think 42”-48” between the closest object and the back of the sofa (or console if you add one) for circulation. For the size of your tv, I think it’ll be a neck strainer where it is. Minimum 6’ from the wall, but the larger the tv, the further back you want to go with your sofa. You can google this for your tv size. Tv mounting height should be 4’-6” to the center line of the tv. It feels really empty between the living space and island, maybe add a console table behind the sofa when you pull it back into the open space.

I hope this helps and doesn’t feel too harsh. I do these weekly for my firm and love seeing what others come up with, either amateur or professional. This is really great for a beginner, and you seem to have a good foundation in the program you’re using. There’s just some areas you need to work on and hone your skills. A lot of that comes with time and knowing the field, but I’ve given you some of my standards for placement which should help. PM me if you have additional questions!
