Like your space and choice of green. Like the green in the kitchen you referred us to. Looks a little darker or less yellow than one you did with Photoshop? You have the same issue as many of us, for one reason or another we end up trying to blend two disparate styles. The couches say man's room, formal, brown wood to me. Your room, kitchen and fireplace say much lighter in colors , style and spirit! If you try to blend the two you will end up with neither. Your purchases to go with the couches will just add to things pushing you in a direction you don't appear to want to go! I'd suggest you find some sofa covers, or even bed coverlets if you can't get covers to put over the couches. I like the colors in the fireplace. Please tell us more about what styles you like.

The blue is awesome (grey is too trendy)! The reason it stands out to you is perhaps because it's the only real colour there. Bring in the blue in a window treatment, a small appliance that sits on the counter, a pretty tray or area rug. Also, it is more appealing often if there are more than 2 colours - so right now you have a white and blue colour scheme - bring in red or orange or fushia - something from the other side of the spectrum (like you did with the yellow flowers but in a more permanent way)!

Your lounge looks like it receives a lot of sun so you might like navy, turquoise, or emerald green for the room. Whatever color you pick, leave the valances (?) above the windows close to the color of your air conditioner, so it won't be too obvious. Use lamps and update the ceiling fixtures. Bamboo blinds might look fun on the windows. Look to the kitchen floor for paint colors in there. It appears the range hood is way too high to be effective. Is that just the perspective?

Pressed metal splashbacks are so rare! This is the first photo I've seen with a splashback like this and I'm really enjoying it.
