And also something called as one-point method she said to practice everyday.
She used to sketch on last pages of book in college.
Pick a point - draw the classroom from your eyes. So it help in human figures as well as perspective.
And for perspective - she did what the teacher taught her.
She suggest to go for a coaching (Architecture focused - one place that teaches for engineering while also the drawing part)
I'll search if she still has that human figure book.
She says she practiced the human figures from a book she got from her coaching.
It was a stepwise tutorial book, line-by-line making human figures on daily basis.
