This eco-friendly tote bag is awesome. The lettering is really adorable and eye-catching. I like the little dots and flashes that highlight some of the letters. It's really whimsical! I also think it's smart to stick to such a limited color palette. I think you've done a nice job of dispersing the colors around too, though the "o" is a bit dark. If you were to make more of these you should definitely chalk or tape in some spacing guides. A more orderly arrangement might look nicer and will read better. If you were to update this particular bag you could add some light heart shapes or triangles.
