The last pic shows really well. Assuming you have antifreeze thats nothing to be worried about, it's clear should be just water..
If you get a puddle under that area that is definately not water it's going to be the front axel seals most likely. Not sure offhand what is on that side of the v6 engine otherwise to be leaking fluid.
Your engine bay is pretty clean, well dry atleast. Get up under there with a flash light and look for the dark/wet spot. Follow the axel shaft up from the wheel, it'll likely be wet on the underside, well wet all over but, there would be something running down it.
Find the drip, follow the run to the dry spot, back up to the start of the wet spot, look for things above dripping, you've found your leak.
If you can't tell the difference between water and oil, best to take it to a mechanic. Even better if you have a buddy or someone to give you some pointers available.
If your willing post up your city and ask if anyone wants to stop by and have a look with you
