That sounds perfect! I do have people ask me about sunflower photos. I've got a great friend who has a couple of fields of sunflowers. He makes a killing letting people use his fields for this reason alone.
Oh yes! I love sunflowers and think this would be a great backdrop for photos. I took photos in a field of wild flowers last year (not sunflowers). I really hope that your flowers all blossom and you take beautiful pictures.
Did you plant new seeds or seeds you harvested? I have a tough time growing sunflowers when I plant the seeds. I feed a lot of birds and in the birdseed is sunflower seeds. I have the occasional flower pop up near the feeders.
