Variation of Erin Go Braugh

I wasn't sure whether or not I liked the coloring on my die cut image on the front of this card, so I did another one all in green for a more monochromatic look. I would be interested in your opinion as to which one you think looks better.

I also used the no line technique on Tilda. I don't like it as well because you can't see the "love" written across the bottoms of her shoes and the details of the shirt and arms are missing. It just doesn't have that sharp quality that using the black ink has.

 

What do you think-more realistic rainbow and sky or the green monochromatic?
