After sharing the plane draft of a suitcase, I will quickly PS a sketch to show the effect to the customer after confirming my own ideas, and will make design deliberation in the process of processing the effect. Not only in terms of luggage, but also in other categories of design, I will use different outputs according to different products, but the general idea is not bad.

Determine the outer contour, of course, some adjustments may be made during the design process.

Large light perception, confirmation of shadow relationships

The whole determines the sense of light, a feeling of the product as a whole.

Add the surface treatment of the existing accessories, etc., and the whole is basically confirmed at this time.

Add details to confirm overall layout

Simple to make a color match
