Hi. Lot's of potential but this room is over-crowded and there are too many small decor items. I like your wing chair!
1) Can you reduce the sectional to a sofa? Either way, move it to sit perpendicular to the front wall. This will create a "front hallway".
2) Place tv on the wall indicated below. Hang tv on the wall.
3) Move wing chair to corner wear plants are. (Do you have 2 of them? If so, place other one on other side of the tv.
4) Add lamps, coffee table and end table.
5) Big thing: you really need to start over on all of the art on the walls. It is looking really cluttery. In addition, nothing is visually working together. The only place you likely need art is on the dining wall and perhaps the first wall you see when you enter (where I think second wing chair is).
For dining room table, I would need to know
-size of the room
-what you are looking for in a dining table: size, style, etc.
