Wall Art and a Request

In this post, you can see the start of a canvas for Brennan's room.  It was the first of three canvases and some letters that ended up taking over a month to produce (I always have too many projects going at once!).  I am happy to report that they are now done and hanging in his transportation-themed bedroom!

I used a Pottery Barn train quilt and sham as a starting point for choosing colors, and I used two of Brennan's tee-shirts and a picture off the internet to help with the design.  I photocopied Brennan's shirts that had a boat and an airplane, blew up the copies until they were the size I wanted, and used carbon paper to trace them onto the canvases.  Then I just got creative with color and had some fun!

At first I was going to wrap the solid paint colors around the canvases, but I ended up deciding that patterns and alternate colors on the sides would have a much greater impact.  I am so glad I made that decision.  It was a lot of extra work, but it was totally worth it.

Here is what the room looked like without any artwork:

... and here is what it looks like now:

(Apparently I need to move the red airplane up a bit since I always bang my head on it and I can't see the artwork behind it!)

Here is what the boat and airplane look like closer up:

So, here is where I need some design help.  When I look into Brennan's room and see this...

... it makes me happy.  But when I turn my head and see this...

or this...

... I'm not so thrilled.  Why? 

1.) The furniture colors are not my favorite.  I hope to someday paint all of the furniture, but I am not allowed to paint while I'm pregnant, and it's just as well because I don't have time or energy to tackle something that big at the present time.

2.) The bare walls are driving me crazy, and I'm sure if they weren't so white it wouldn't be so bad, but since we're renting, I'm kinda stuck.  I do plan to infuse some color into the room by hanging (still unmade or unpurchased) panel curtains and a (half-finished) red bed skirt, but I really need to figure out what else to put on the walls.  I have some ideas, but I'm stuck on implementation.  I would love to get a big red barn star to put someplace, and I was thinking of incorporating these photos somehow:

I could do them framed in color, black & white, or sepia and use all of them or just one, but I'm not sure how to arrange them.  I thought about a floating shelf, but I'm just so unsure of what I want or where to put it where it wouldn't look like an island on a big white wall. 

I need some design help...  I really want to get the room done by the end of July so I can focus on the nursery in August.  I only have fourteen more weeks until baby girl gets here, and there is a ton to do!
