Is the wall sage, teal or gray? It doesn't seem to be turq because the lamp doesn't match. You might consider adding solid bedding in the wall color, which I can't really pin down on my monitor, to tie things together rather than gray, unless you up for painting.

how about a texturey blanket in a strong color folded over the bottom of the bed to limit the light color of your bedding.

I would get gray sheets. Or white with gray dots or stripes. For the wall, here are some pieces from west elm that would look awesome. Specially the bull or waves in my opinion.

Keep your white sheets and go with a gray comforter and pillow shams. Abstract print by Jack Diamond sets the natural mood in your room.

You go Gregory. Nice job with the paint and furniture. Something unexpected over the bed.

I went looking for charcoal and white shams and throw...found this from room and board that could help balance.

Love the furniture and wall color btw

Sure ( the painting comes in different sizes too ) http://www.art.com/products/p17721726448-sa-i9458558/peter-pastel-waves.htm?upi=ap9458558_pc0_fi0_sv6_it1_vrv1

Nice work. Love the comforter. My hubby and I both like White on White. There is a great Hotel on the beach in LA that has their rooms decorated with White on White bedding. Wood, and a few beach Colors. Very soothing space. The painting Mark suggested is great.

I like the white bedding and curtains, and you might keep all this for the spring/summer. I would suggest you get a turquoise throw or turquoise coverlet to put over the white bedding, provided you can find one that does not look too feminine. I do like your idea about grey sheets and accessories, and a grey bedspread with some white border stripes would look fantastic. Since turquoise is your main accent color, as in the lamp, it would be great if you could find a large piece of art work that includes most of the colors in the room. Do you like beach prints, western prints, or landscape scenes? I believe you will find your room colors in these subjects of artwork. I would suggest having a large print placed in a frame that is painted white with a bit of grey wash or shading on the frame and then displaying it above the headboard.

Good on the gray sheets. I hate to even mention it, but (on my monitor, at least) the gray of the pillowcase looks a bit too warm. It should be closer to the gray of the lumbar pillow. I adjusted it below.

I'd go simple on the art, graphic black and white.

The color in the blue lamp adds a nice pop of color to your room and it would be lovely to have it repeated in the artwork and even in other acces

I do but not sure if there is a size that you will want. This art is more square. I love the color of blue in your lamp, obviously you do too because you chose it :) and feel that you should try to repeat that color in whatever art you choose. I feel that it would tie everything altogether so nicely http://www.allposters.com/-sp/Deep-Waters-I-Posters_i8026825_.htm
