I love a BM blue paint chip called Clear Skies. I'd love to try it in a bathroom or nursery someday. According to colorcharts.org, a similar SW blue would be Bubble 6770. My sister-in-law picked more of a medium blue for my nephew's room, and it really seems too dark for a child's room. If you want cheeful, I'd keep it light. Checking out the blues on the favorite paint colors blog might be helpful, too. SW Waterscape and SW Tidewater look pretty and cheerful. Here is a link that might be useful: Favorite Blues

Why not hang the pic over the bed and the mirror(s) on that wall? Mirrors over the bed are bad feng shui. I'd like to see a big, red, glossy ceramic cache pot for the plant. Pick up the reds in the pics. Leave the armoire as is, but change the hardware. There is some fun and funky stuff out there and it's a cheap way to update. With the round mirrors and the circles in the print, I'd go with round accent pillows on the bed, and prints with a more modern flair...maybe some bold geometric prints. That would play well with the dentil molding squares, your very squared windows, and the curves in the bed. I don't like the metal end table, but I like the shape. This one is too lightweight. You should look for something with storage capabilities, since you have a lot of stuff on your nighttables. I think some matchstick style lamps with a-lined shades would be good. I really get a contemporary, geometric vibe in your room.

I love the idea of a blue grey, but you just need to make sure it’s not too dark. Darkness will make the room feel closed in, and you have such great space, you don’t want to take away from that. We painted our son‘s Room a light grey from BM, called Silver Chain...it was so light and airy...and as he’s grown we’ve been able to grow the overall design. Good luck!

I love that he reads but yes I need to have the sizes of the walls and if you use graph paper it is quite easty to do a scaled floor plan just measure the floor all 4 walls make sure the measurements are clearly marked show where the window is and its size where the cabinet and also if it can be moved. Maybe some pics of the shelving you are asking about too.I for sure can't see putting shelving on the wall above the top bunk bed but have you looked at trundle binks then there would be a big drawer under the bottom bunk for tons of stuff. So like this but no mattress in that bottom drawer.And even the bookcase at the end could work.
