Doesn't remind me of an Ikea house at all.
I have nothing against Ikea, they have great stuff for good prices, but this is much more stylish/better quality. You've chosen beautiful furniture pieces. However, it does lack warmth and personality.

You could move the sectional away from the wall, move it to the right or turn it around as suggested above.
You need to find at least one large piece of art that you love and that can go on the large wall where the sectional is now. You also need art above the black cabinet. I'll see if I can find some suggestions for you. You also need lighting. Some floor lamps and one or two lamps on the cabinet at least.
