Art prints for Baby's nursery

I've spent A LOT of time thinking about the baby's nursery and how my millions of ideas could possibly work together. I've given up on some of them because I realize it's just all too much for a tiny baby's room. John and I have modern taste and our home is full of pieces from Crate & Barrell, West Elm and Ikea. We like clean lines and neutral colors with pops of bold colors and patterns. Like our bedroom– blue-gray walls, white linens and dark brown furniture, with patterned curtains and bright orange accessories (vases & pillows, and hopefully soon some artwork). Naturally, I've wanted something similar for the nursery but as my ideas are beginning to take shape, it just doesn't feel quite right for a baby's room. I need to add more baby-friendly elements, without it being too... Well, baby. I am in love with the argyle bumper, polka dot bedding and solid teal curtains we have and am now looking for other pieces to compliment the colors and patterns without looking completely random or too busy (this place needs to be calm and peaceful, not hectic!) I've scoured the internet and my favorite handmade website, Etsy.com, for kid-friendly art prints and finally found a set that John and I both love!

There's nothing better than cute but silly looking animals :) I think this will work in the room since the background colors are blue & green, like the fabrics we have, but the content is perfect for a baby boy. I found other pieces that would also be nice, since they are the right colors:

Once we get the crib and glider in place (coming any day now!!), we can figure out exactly what will go where. I can NOT wait for all this to come together!
