If you have bare walls, then choose colours that won't clash and would tie in wiht the room. Then pick out colours you actually like and pick a favourite. Most everything will go with Grey but contrast is usually more visually pleasing.

Having been brought up in a Lockwood home I can appreciate your love of the wood. I notice you have a light green bench and that would blend nicely with some similar colours in the room. I would consider having your cupboard doors replaced or sprayed to compliment the bench or visa versa you can have your bench updated with a new finish to modernise it. Perhaps you could just price out the cost of a new bench and leave the rest of the kitchen as it is. The odd bit around the dishwasher looks weird and that might be able to be fixed by curving a new bench into a small breakfast bar type set up. If there is room I would also reposition the microwave to the right of the cook top and use the existing space for a display or a lovely pot plant.

Far out! This bathroom is amazing. How did you make the light? Definitely a work of art within itself! The glass door is also amazing, I'm such a fan of stained glass in the right circumstances, and this room is definitely the right circumstances. I'm in love.

What about colour , character and personality ? A splashback with a pond and a tree may be great , or look naff , as the Poms would say . Potentially , its on the right track , but look at pic 3 . Gone to sleep yet ? Probably $30k spent on nothingness . Now look at pic 3 , and imagine your splashback . Even if it is ( cringe ) black and white too , it will actually add to it . A bit . I don't like the particular light used in pic 1 , but its got character , you notice it , it is not totally bland . Pic 3 is .
