Are these the sprites to go on the map (say, when you find an item), or in your inventory? If it's only for inventory, this doesn't matter, but if it's for in-game as well, I have a slight issue.
That being: I've started working on character sprites, using the style rules I know of. Knowing the relative size of the character images on the wiki, tile size, and the size of item/weapon sprites (I am assuming in this that the item/weapon sprites are both for inv. and in-game use), I used a calculator and figured that, for the purposes of this game and in the interests of keeping things proportional, a foot is roughly eight pixels. This means, while the small graphics are fine for items (food, potions, what have you), weapons and equipment on the whole really are going to have to be drawn larger in order to not look silly. Real longswords are often around 5 feet in length, for example. Of course, dimensions don't have to be adhered to strictly; the characters are drawin in SD, after all (in particular, very small items can and should be disproportionally large). But some degree of proportionality must be maintained, if things are to mesh well. Which brings me to my next question, which will have a huge bearing on how I work on some of these images. In item/equipment sprites for in-game use, can the sprites be larger than a single tile? I am thinking here of suits of armor, of longswords, of polearms, of staves...things that are generally longer than the three to four feet or so allowed by a single tile. If this isn't possible, and I know saying this won't make me any friends, then you should really think about restructuring whatever makes it impossible, or risk it looking silly.
