Here is what I mean Ivan. I have provided your original image you provided then the up-date of what it should look like. Cause if you don't fix it, the overall result will look squished.

Your Version:


What it should look like:


Bearing in mind, this was done quick just to show you. Hope this helps.

Ah.. Big thanks Andy.. I got what u mean..

hmm, but doesn't it means, it change a bit angle from the original images? Or just mistake of my eyes.... , but yeah, the correction looks better than my version.. Okay, I'll correct it soon..

O yeah, for temporarily highlight/shadowing, is there correct.? I know theres a mistake on the rear arch(looks like a fail arch huh?), so i try to startover the hl/s after the rear arch looks well.. But before doing it again i need know if that hl/s yet corrected or not..

(sorry if my english not well)..

Highlights are okay so far, work more on the details of pulling the car together then I'll be able to advise you from there. Your doing well Ivan, take time on this and pay attention to detail.

Sorry Andy, here I found a little stranged between ur correction and my version..

here, the perspective of the bases...

I think the position looks like these:



Then, should be like these isn't it..?



CMIIW..

(sorry look like I wrong on the rear bumper line)

The way I usually go by, it doesn't matter as long as the car isn't squished. If you continued on with your version it would look likea cartoon car, where as my one I posted for you keep you more on track. However, it's up to you to chose who to follow, but I highly doubt I am wrong

Well ya.. Uhm.. I must finish it first to proof it... hhe.. sorry Andy, but don't worry, about ur suggestion I'll use it if there I wronged after I finish it half..
