Ok, so this is my first attempt at photoshop really so go easy on me. I'm pretty happy with the results. I've worked on it for a while tonight and there are still a lot of little tweaks that I need to do. It's tougher than it would seem to take a whole jeep out of a background and smoothly replace it with a 350z,

. Any ways, here are the original two pictures:
Jeep pic-
Z pic-
Final (for tonight) product-
I need to learn how to properly light and blend the picture of the Z into the background without it standing out so much. It also wouldn't hurt to get some practice with blending the background. I think the result would have been a little cleaner if I'd taken more time. Any ways, more to come hopefully as I get the hang of photoshop.
