First, pull the rug in if you can so edges are by feet of sofa and the bring loveseat in so front legs are closer to rug. The rug is a bit too small but will see if we can make it work by adjusting it. Lovely rug. Also the lamp, it is in a very awkward position. I think it should be angled to the corner of where the 2 sofas meet. Truthfully, I am not a fan of those lamps, but someone may be able to tell you the best position. Have you considered a coffee table or ottoman for the space? Maybe something with some color and then tie in those colors with pillows and accessories.

Take photos of the complete room please and post.

Here are some options for ottomans and color

Nice teal

You can do red, blue, purple, navy, yellow or teal and all will go with room. Add pillows in same accent color. Let me know if any appeal to you I can give sources to order.

I would suggest de-cluttering, removing the items blocking the window and the plant, it is awfully large for the room, instead you can add an accent table beside the couch. I like the pink, you should use that pink as your accent color and bring in some art and accessories to match. If it is in your budget, I would change the window treatments to plain white and change the rug to something more sleek that better suits the space. Hope this helps!

You don't have any tables or lighting in room. As I suggested bring loveseat in closer to sofa add end table and lamp between them. Not sure if that tall plant is real, but growing into ceiling, remove it and find better area. Move the statue and barrel from in front of door and move to end of sofa in corner under window. Remove the stuff off the window sill.

I would remove the large tree, pull the rug closer to the sofa, gets some great end tables, table lamps and coffee table. I like your floor lamp buy would suggest moving it to the corner between the sofa and the love seat. you definitely need some color in this space. I would also remove/move the stuff in the window to an end table or out of the room. I would move the urn with the white reeds in it over where the tree is now if you don't want an end table there.
