Rabba you know I always have an opinion and how much I admire your work, more so for the fact you do it for nothing. I do however have one minor complaint and I hope you don't mind this hun.
The first poster is beautiful if not for one thing I find hard to overlook.
The hand coming out of the grave holding the stake is a beautiful image but due to how it portrayed, it was initially hard for me to see the graft of the hand. It seems rather too smooth, succinct and tends to blur into such a mold that it doesn't grasp the look of a hand. It takes away a little of that realism which would make the poster absolutely stunning. If fixed then wow! Sorry for the complaint darl x
To the second one I have no quibbles, it's flawless in the best of ways. The army outfit, the dogtags, the scarf and blood in such familiar colour manages to keep the poster interesting and different. It's not horror but in a way it is. Love the second one to bits. And you know my opinion on the Scream poster. 
Be aware even with that minor quibble I still think your talent far outweighs that much of Hollywood. You have unique designs, flair and a true understanding of the horror genre that sets it apart from the usual posters. Like Garden said, keep going and try submitting, someone is bound to notice what you can offer.
Looking forward to more posters!
