Thank you in advance.

The color is too new to me, I would say mid 20th
I would say Guangxu revival of the Kangxi period, the ones I have they also copied the foot rim so this could be a later copy as Stevensaa has already mentioned.
The color and painting quality make it look rather 20th century. I must say that the late Qing dynasty (Guangxu) has seen some better painting, thus I have some doubts whether it still could be Qing.
Yes, the color blue is a little to bright for late Qing.
