How Do I Get A Yellow Front On The Class 465/9 On Xbox

I am making a livery on Xbox but how I make a yellow front on the 465

 

Just add a square , then put smaller squares around the edge of the front

 

you go onto side view and then you see the panel where most of the liveries yellow point starts and add squares and circles to make it look right

 

You can use a combination of semi circles and squares and adding extra features may help.
