cool chop i like the fact you used a bg that makes sense with the cf hood , there could be a tree on the left side witch would provide refs and the light at the back suggests there are more lightpoles so the light on the hood makes sense..
brush is decent but it def needs more
first some parts have been brushed to soft , better like this then everything too hard but still some area's need more crisp lines to define some shapes
then you need to work with lighter and darker area's
take the side skirt for instance > its one tone blue with some cloned tarmac ref's
just try this >
select the whole skirt , make the bottom a bit darker along the whole length and at the top make a selection aling the top line and brighten that (give it hightlight)
most people think reflections are most important , nono its the shading and hightlighting that makes a body pop and look realistic
your front bumper has got highlighted area's and shaded area's , the whole side of the car needs that as well
this waws just a quick and simple explaination just try some stuff
btw seeing some work in beginners and in inter i think this could already be promoted to the low intermidiate level >>
