well nice base pic
i think the rims are a great choise , they fit the car great
i'm gonna try and explain some "mistakes" so you can use them in the future
the rear rims is slightly off anlge
the roll cage is nice , the fact you try this also , but it actually needs to look like its inside the car though
also the cage is way too bright it needs to be really dark since the interiour and window have no real lighting
also the cage on the top end of the car would not be visible really there is always a black headliner part and then the sunband witch is in the window (the darker band at the top) is now behind the cage
the front bumper , design wise fits the car great but its way way too bright , it needs to match the cars paint
to start with you would have to select the blues and get rid of them (image adjustments > replace color)
then give it the tone the cars original white paint has got (select the white of the white closest to the front bumper with the eyedropper tool and what could work easy is to brush over it with the colo replacement tool
there are so many ways but for your skill level this works great i think
then lay with the darkness of the front bumper so it matches the ori paint
well keep it up
