Nzr,
thank you for your submission. I like the colors, the symmetry, and the font but for advertising purposes I dont think the font is legible at first glance. I like the colors of the butterfly but if I were to advertise in a black & white publication I dont think the butterfly would stand out so maybe a variation in color. Could you please try another font and maybe ad some texture or depth to your butterfly. I encourage you to resubmit your design.
Thank you for all your time and efforts.
