Medicine cabinets have come along way in recent years. The best option is to get a frameless style and integrate it into a wall of mirror. You can mount sconces thru the mirror on either side of the cabinet. If you have walls on either side of the sink, you can put the cabinets to the side, integrated into mirror again. If you have an open wall in your bath, yo can get an extra tall medicine cabinet to hold loads of stuff. There are loads more on houzz photos. Just search medicine cabinet. Sometimes you have to hunt for the cabinet because they are so well integrated. Robern makes some of the best frameless styles, but there are a ton of others on faucetdirect.com. Many even come with integrated lighting for a very modern look.

I love LED lights because they brighten up a room with ease!

Cabinets with greater depth and access, high pull-outs with closed sides and wide drawers give extra space in the same footprint. Increase your storage space with DYNAMIC SPACE ideas from Blum. Add up to 30% with deeper pull-outs Add up to 15% with wider drawers Add up to 55% with higher, closed in sides

Personally I wouldn't hang black curtains with this colour lounge suite. I would also take out everything that you don't need in the room as it is too cluttered. I actually like the wood as it matches like Bernadette said. I see that you are adding pops of red in the room. How about a picture on the wall with that colour in it, as the walls are quite bare. Are you able to remove the computer desk and chair? I love big mirrors in a lounge room too . . . The programs that I have watched in NZ, ask 'what is the hero in the room?' So I think you need to ask yourself this and work with that, going forward. . . . The only comment I can make on the skateboard is I think it is placed too high on the wall.
