  My passion Everyone has their own passion. My passions are art and cooking. Since childhood, I have learnt drawing and painting which had both modern and traditional arts. I have learnt one-point perspective, caricature, cartoon, paper collage, traditional art forms etc. I made these art works using colour pencils, crayons, soft pastels, water colours, oil pastels etc. Nowadays I am trying to draw traditional art forms like Warli, Madhubani, Kalighat, Mural, Pattachithra, Gond, Miniature etc. I was so excited when I received India Book of Records. I make art works on A4 size or A3 papers, cardboard, canvas etc. I will be making new and creative art every week. I am planning to do certificate courses and join classes to become more perfect. Art makes very happy and gives me satisfaction. I feel so proud. My other passion is cooking. I love spicy and lip smacking dishes. I learn cooking from my grandmother, mother and youtube channels. I also watch Master Chef Australia where the p...
