Very impressive, but a few problems.
Very nice work, the faded colouring and scratch/grain filters really contributes to the aesthetic. I really like your illustrative style and your skill with poses and shading is sublime. Just a few complaints - the composition seems a little unbalanced, top-heavy and leaning towards the right - I understand you're trying to bring out the Triforce in the background but, if you look at the original Raiders poster, it makes use of implied triangles with a busier composition down the bottom to create a feeling of stability and produce an even composition. The distinct lack of substance in the lower left corner makes the composition slightly uneasy. If you were to add another character or a temple or something there instead of crystals which seem out of place and overly simplistic compared to the overall composition, it would really make it a lot more harmonious.
Also, the scratch, grain and fading effects ought to have been applied to the "Triforce" and "Gods" in the title as well - as it stands, the words are crisper than their surroundings and therefore stand out a lot more and take away from the air of authenticity. And the text up the top was probably a poor choice, it looks like it was added as an afterthought and is reminiscent of internet-meme style text caption.
I really think the stars system for artwork rating is stupid, so don't think I'm giving you a zero - I just don't think it's fair to assess art based on a numerical system when art is an expression of ideas - to me, that would be like assigning a rating system to the different schools of philosophy.
