Its a nice fake! However, I think with a little transform tool, and maybe something to smudge that skeleton back down into his throught once at an angle like the liquify tool in photoshop, and you could have it it perfect.
Good job, Kev. I gave you 3 dragons since someone really gave you a low score. Anyways nice effects. The lifebars are perfect, the effects are nicely done. But I don't like the bg pink, neither Jax pants. Make them red because it looks better. One thing that will probably made your fake better and realistic is you should of added some shadows. But this is a decent fake. Awesome job.
