I presume this: http://bulbapedia.bulbagarden.net/wiki/G...hant_94%29 is your source?
(I would not mind at all if you made it a habit of linking to your source)
In which case, I think you ought to move it a little more to the center...Its fingers seem to fan out to much in your sprite, and the arm itself might be too long (Gengar's arms are pretty stubby). Its horn could be more slanted, and generally, I think the body isn't quite at the same angle. The top right corner also should start transitioning into its horn if it was placed like that, otherwise, it looks as if it was bald on that side. Again, this is probably related to how the sprite is at the wrong angle. The lighting also seems to differ substantially from the original, from what I can tell.
As for Jolteon, there's something that bugs me...The sprite looks kind of...round all around? Like, the ears and the tail spikes are all nubby. The card doesn't show any shine around Jolteon, so I don't think it needs that white outline, but maybe that's part of the style. Isn't the snout a little too long, too? The background seems a tad inaccurate, especially the lower half. I'd say it should have darker colors, and it doesn't really reflect the pattern of the original card well, but that might also have to do with the style.
