If you are really passionate about art, then just think like an artist, focus on the things around you, observe them, look at the way they are made. As an engineer, design is concerned with how things work, how they are controlled and the nature of the interaction between the people and technology.

Students can also choose one favourite topic or one medium for detail practice like (Pencil, Pencil Colour, Charcoal, Oil Pastels, Oil Colours, Acrylic Colours). As an art student I would also suggest you to buy this book - The design of everyday things. The best book suited for all the designers. The Design of Everyday Things shows that good, usable design is possible. It's a really nice book and will definitely help you in future. Also keep in mind that you make a separate portfolio which will include all your sketches and creative designs. This will help you a lot in future. Hope the information was helpful, Thank-you.
