You've done a good job! Too bad you have that monster sofa and chair to deal with. You could gain some floor space by hanging the TV on the wall without the white credenza.

I love it! I agree with paint color. Too much purple in there. How about something that will complement the warm brown of the leather furniture? I think the paint you have right now would look good with a more modern design scheme with light furniture which probably isn't in your budget. Paint is cheap to buy. Get some paint swatches and hold them next to the floor and leather sofa. It will help you see what looks good. Pottery Barn colors from Benjamin Moore paints are pretty fool proof.

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)!

My last household purchase was new sliding doors to the outside from my dining room. This then led to the building of a deck, new railing on said deck and existing terrace, new blinds as the old window length curtains no longer did the trick, then the paving stone path to the deck from the garden gate, some new planting to accommodate that, AND outdoor lighting for what has now become an alternative entrance to the house! Oh, and painting as well. So I can liken my last purchase to a bit of a triffid - it kept growing! But SO worth it! It has added another room/space to my house, increased light and warmth, added value and created a more welcoming entrance than before. Love it!
