On quick glance they are cool, but some basic stuff is not really up there to be honest.
On the truck, tires and wheels are not that good quality wise and color/shadewise they do not really fit. Also lack shading. Lowering is done well and it looks like it could be made in real life with airbagsuspension.
Nice bg change, apart from the smudged? old reflections. Those make the whole hood and part of the roof look different color or "dirty".
Otherwise pretty clean work, but some of the "shortcuts" are clearly visible here. Both would have benefitted from more care quite a bit.
