Hi @jannatmou! Thanks for taking part in the challenge!

I don't know if that bluing in your shots was intentional but it gives a fresh tone to the drawing that immediately draws attention when looking at that vase with sunny flowers.
Good step-by-step of the drawing process.
I think that the hard strokes in your way of drawing as well as the way in which you fill the entire page with a vertical and strong composition go very well.
It seems to me a good drawing, it has strength and is well-located on the page.
Congratulations!
