In my opinion, I like the way it looks now.
Question, is the White background Kona White Cotton or WOW (white on white) because if you tea dye it now you may not get the effects you wanted and different teas make different shades of color and depending how long you plan on soaking the fabric in the tea water.
Orange tea makes a pretty buttery color. Lipton tea bags make a total different color, black tea almost a Grey color, experiment with your tea wash. Once the color sets in, it may be hard to wash out, even if you decide to use bleach later at some point.
Make another one and tea dye it before putting it together.
If you use WOW you will see the imprint on the background and it will have a nicer look. Just my opinion.
I like to tea dye.
And the colors now will run together, leaving a blotchy mess, believe me, I've done that too.
