I've had people elsewhere say the parchment and maps look like they're "ripped off a shitty flash game"... what do you think?
Might be TL:DR territory, if so, skip to the last paragraph.
That's likely because the edges are all darkened... This makes it look unreal, because paper doesn't work that way... Neither does parchment, for that matter...
to make it look more realistic, go ahead and take a piece of paper and put it into light from a source other than directly above, prehaps have a lamp next to the table it is on. Notice the pattern of light. You'll see that there really isn't much difference in shadow at all because you are looking at a flat surface. The only way you would have such deep shadows would be if you had other items casting them.
Also, I like how they looked ripped, but they also don't look
believeably ripped. If you wanted to do that, it would end up looking more personalized and unique while also giving you a reason to put shadows (because a ripped piece might be curled up and therefore casting a shadow on another piece.
The map looks very plain, perhaps you should draw a map, rather than simply placing points of interest on a blank page covered in squiggles.
In short, Complexity and and attention to detail breeds originality, so make sure that you take a few minutes to get an idea of what you want... I would suggest you actually make a menu out of real paper using a light source when remaking this menu so that you get better results. Also, I would suggest actually scanning samples of your own writing to use in the menu to make it more realistic and unique.
