Agar meri drawing achhi nhi h to kya m for bhi interior designer ban sakta hu
Partially No.
As drawing is one of the tools to show your ideas, senses and plans and it can be developed throughout the practices so I would say if you are very much interested to become an interior designer so your passion to be an interior designer and eyes to see colors, textures and space matter as you need to practice a lot to make yourself good at drawing and I am sure if you do this, you will be good at it.
Good Luck!!!!
