Hi. You wanted to know what skills you need to build up on to get a job. I think you need to be able to do what a Senior Artist does if you want to break in. The reason I say that is because most jobs out there are for people with those abilities.
Get better at texturing. Try to only show models that are fully textured. Of all the characters the only ones that stand out are the RTS soldier but the skin parts need a bit more work, and you should tweek the model's face. It looks a bit too square at the moment; and the alien from Pitch Black. That alien needs to be textured though or it will get dismissed. The other characters if you wanted them pick one and polish it up. They are all the same quality and style so they would get dismissed if they are not all polished. Keep in mind that art teams don't have time to look at all applicants so if you don't impress them you'll not be considered. Your props seem to be your best work at the moment but take out anything not textured.
The biggest problem I see with yout site is your presentation. I refer to how you are showing off the models. Right now your presentation doesn't help much. I suggest you also show your model without a background since they can be distracting. I liked your backgrounds though. I suggest you look at other sites of artist you really like and see what they did. www.guberski.com
might give you some ideas on how to show off your work.
I hate this but it's true, modellers are a dime a dozen in the Game industry! You should make your work look like things found in Unreal 2003, Doom 3, HL2. I am mostly refering to the texture quality. Hey if you can texture like Kenneth Scott you won't have an issue getting a job. So getting your texturing ability top notch is your top priority, then if you have time you should learn to animate. Later.
