My entry for the VFXTalk.com VFX Challenge. They provided the snowboarder, participants had to make everything else on our own. The setting is that this is a soldier of fortune, sent to rescue Captain Kirk from the snowy planet he crashed on in Star Trek. This is what I came up with. The ship, canyon and bridge model were modeled and crudely textured in Lightwave, then everything was shipped over the Nuke for compositing.
For the most part, I like how it turned out, but I wish I had access to better stock footage (like, real explosions instead of particle effects I had to color correct). The explosion at the end is the only actual pyrotechnics.
