This is nice actually. the only thing that could be improved is the text. as you have observed. the text "Cosemos Juntas?" you have used a black color. and the background has dark shade of green. This makes the text blend with the BG making it unreadable. You could change the text color to a lighter color (e.g white, peach etc) to have Contrast. Contrast is important in all aspects of design. The rest is very nice! Good Job on this!
