I finally got around to fixing some of the default textures that I didn't like and despite a complete lack of artistic skill I think they turned out alright. So I decided to post some of them here to see if anyone was interested or wanted to offer suggestions.
The different weapons: Spiked club, Battleaxe, Shortsword, knightly longsword
I've seen a couple of battleaxe textures here before, but they all tend to be designed as large, ornate fantasy pieces. Historically battleaxes tended to be extremely light and sharp (and almost never double-bitted) so that they were fast to swing and easy to carry.
Iron mail armor
looks cool but I wound up not using this one simply because it didn't combine too well with the other armors,
I also retextured the gold and iron blocks to look more like ingots. I'm still not sure of what to do with the diamond block.
I also switched out all of the stupid looking blue diamond textures and made them look like iron tools and armor, However at the moment they are still a bit tricky to tell apart.
