Dear Ehsan! Thats a nice macro photo. Well done!
A little note: This plant names Chaenomeles(as its scientific name) But it is famous as Japanese Quince( not Queens! Queen is the king's wife but Quince is a fruit that we name it "Beh" in persian) This plant is also a member of apple and Quince family botanically. You can find more information hare!
Excuse me!
