Okay replying to a lot of stuff.
The cobble and stone brick are amazing. The iron golem is cool but maybe add gears on arms/legs or something. The theme is either 'rusty old stuff' or super metal tech RPG. It's kind of in between right now. That wouldn't be too bad actually. Maybe make mobs that look diseased, like robots, or half dead things fortified with cyborgness. Also, feel free to make as many as you like. We can never have too much.
Okay! The pack is up on MinecraftCustomizer, but in order to get any of your textures on it, you must PM me the texture and also what you want the descriptive name to be. e. g. Grassyfilth's Rusted Iron Block, Visual_Argonian's Diseased Creeper, SPSilcox's Broken Stones.That TNT is amazing. It just screams the message of this pack. The iron golem looks great in-game, I tested it. The Netherrack should probably have a different palette, but whatever. Great TNT. www.minecraftcustomizer.net/pack/TogetherCraft
Updated customizer with TNT, Netherrack and a stone by me. Lemme know what you think of it. xIBloodIx, that's pretty funny. Maybe make your next textures a bit less saturated or less cartoony? I do really like them though, I would use that pack. SPSilcox, that spider looks... Iffy. I think that your second idea is better.
