Beautiful choices so far! I think you're fine mixing styles although I'd say I would prefer two pieces from the cream colored line rather than mixing these two. I'd also bring in more acent colors through the rug rather than sticking with only the nightstand color.

Whichever wall color you select I would be sure it is at least 1 shade lighter or darker than your furniture to create contrast between your surfaces.

Thank you! Do you consider the dresser the cream colored line? I love the idea of more accent colors ok the rug. Thanks for the wall color tip.

Sorry for the confusion - I meant the shorter of the two, photo is below.
