Begin by sketching your design. The line work doesn’t have to be the best as you will go over it all using paths. Try to include as much detail as you but don’t worry too much, the point of this is to develop a design as well so its a good thing if ideas come to you as you work. Scan the sketch and save your file. This particular file is 3500 pix wide if you’re working with anything considerably larger or smaller your results will be different due to brush sizes.
Start by redrawing the lines using paths then hide the layer with the original sketch and on a new layer stroke the paths using a brush 1px wide. Rename this layer to ‘lines’.
Using the magic wand tool select the areas which represent the main bodywork/metal areas. On a new layer use the paint bucket tool to fill in these areas.
Using the same method as in Step 3 fill in the rest of the car putting each area on a different layer.
On a new layer use the gradient tool to create a background gradient.
Download some wheels from designermart.co.uk. Extract the angles suitable for your design and position them.
Fill in the areas which are in shadow or shade. At this stage don’t worry about the gradient of these areas.
Select the eraser tool and set it to Soft Round Pressure Opacity then start to erase the top areas of the shadowed areas. The premise here is that the higher areas are closer to the light so the shadows are lighter.
On a new layer add a gradient coming in from the right hand side of the car and a little dark areas on the roof.
Erase parts of the gradient from the right as shown.
Add a little shadow coming down from the beltline to give the side of the car some shape.
Add some more shade to area above the beltline and the hood to give the areas some depth and shape.
Add some shade to the wheel arches and areas underneath the lights.
Select the soft round pressure opacity brush with flow set to 4 and color set to black. Select the a-pillar and spray some color as shown.
Change the color to white and add a splash to the bottom area of the windows.
On a new layer create a white outline for the grille.
If you imagine the grille is a recessed piece of chrome imagine which areas would reflect the sky and be bright and fill in the walls accordingly.
Turn off the ‘lines’ layer and on a new layer stroke the bars in the grille.
Retouch the lower outer corners of the grille bars to give them some interest as shown.
Stroke the bars paths again but this time with a thin white soft brush to create a highlight.
Set the eraser to Soft Round Pressure Opacity and erase the outer areas of the bars.
Using the wand tool select the light bulb circle and using the brush tool with Soft Round Pressure Opacity options to create some shadow.
Add a little shadow to the top of the light to give it depth so that it looks light its set in from the hood.
Select the rings around the light bulb and use the brush tool with Soft Round Pressure Opacity settings to create the highlight areas.
Stroke the light detail with a white color.
Go over parts of the light details to give it the impression that its high gloss chrome.
Repeat Step 26 on the other side for the other headlamp and add a stroke for some spot lamp features.
