For an artist position, I think the presentation of your website, really works! People say it doesn't matter, that they're not judging your web design skills, but I'd say it's bullshit, a good presentation means you care, and you have a good eye for artistic webdesign as well, which is your case. (Loving the background)
As for the art content in itself, the two characters you have in there are pretty good for a entry position artist, and it shows you can do more and better in the future.
No crits on your Maalik character, maybe I would choose a darker background like you did for the hazard suit. Oh, and the textures have a white background? Don't do that it's weird, just use the average colors of your texture in the background, it's better for mipmapping.
As for the hazard suit, I think it's a really cool character, but you really can tell how poly the arms are from that shot, good render tho!
The fire extinguisher is pretty bad piece in comparison to the characters, bad presentation, the texture is blurry you can specially see it in the text, I realize it's a 512*512 so in this cases you should use a overlaying decal texture to create text and don't put it in the texture itself, also there's random scratches everywhere which is very unrealistic and the wheels are very low poly.
Good luck, I'm fairly confident you'll find a entry level position in no time!
