Your pictures are unbalanced altogether in my opinion. There shouldn't be anything hanging on wall to the left of the TV. That space is small and can be left as breathing room. Also, in the second picture it looks as if the wall art to the right of the door opening is squashed into that space. Can those 2 pictures be hung side by side on the TV wall, with the centre of the pictures about 60 inches up from the floor?

My other suggestion would be to remove that decorative table in the play area, and make that a spacious play area where the stander can also go. The sharp corners of that table should be away from little heads too. The photos sitting on top of it might look good hung close together, to the right of the door opening. I would take the tall vase and put it to the left of the TV. It would fill that corner nicely, and be away from the play area.
