You’ve got sunflower stalks with differnt amount of leaves which is good, but the only thing you might want to do is angle the actual flower’s differently, should make it look a little more natural
You are right. Now I see that this is too uniform. I created few version of sunflowers and also placed them on different high, angle etc. but now I see that I should have done this more “wild”. I will remember about this in my next project. Thanks
