its good, but very simplistic , add more details its in a garage surely there is more to reflect on the car

doors look plain and hood , bumper and what not
The colour could have been brighter in stauration as it looks more brown the orange,
( not sure if this was what you wanted )
Also wheels are pitch black like dark side of the moon black, like falling into a well 20 meters deep black! lol , try add some highlights to them make em brighter
Also I think the car sits wrong in the background, compare to the floor and roof it looks wierd, i might be wrnog ,.
The interior is also pitch black surely if there is that strong highlights on the car body itself it should be lighter inside interior.
Also just to highlight the bits that need reflections are, side part of the bumper, side skitr , and mirror and wing . they seem a bit bland.
Also, wheel arch at the back looks like a flat piece of paper, while front has debt, try and add that same realism on both inside arches.
soo,,,,, I think thats it . I hope you take this as contructive critissim, and dont judge me ^^ as I just try to help you get better.
( PS sorry for bad grammar )
