Hello @minahilrana welcome to Creative Sunday.. This is a really beautiful sketch you have here, although I noticed you didn't list out the materials you used to make the sketch, you only wrote about the pencil.. It's always best to list the materials for better understanding.
Also, we advise people to either take a picture with their final drawing or at least write your initials on the drawing so that we can know for sure that they're yours 🙂.
