OPI - Chocolate Nude (Another said Dulce De Leche)? I like this color in the photo. I think it's Chocolate Nude. Dulce de Leche looks less it has less pink in it in other photos but Chocolate Nude looks darker in some photos too. Need to test in person.
Keep the branches exactly as they are, ut, instead of the butterfly wing, make that side a cluster of monarchs flying with some landed on the branch stretched out. Also, shading it so that it pops out and making it more realistic looking.
