@csaba_kissi front, then when u settle on the design and features implement them, designing back first is usually a mistake since you'd divert paths mid building
@markproduct honestly none, the way the cta blends looks off. Maybe you should keep the blur to the background, putting the emphasis on the button, also the price being above the cta is bad, you don't want the first thing for them to see is the price but the cta instead
