Can you please add some pictures to it? We don't really know that much of how it looks at the moment. We only know that it is original (I suppose the default textures of Minecraft) and in the resolution 128x128
This was already posted somewhere, where the guy actually said in his thread he used a filter(so at least he said he used a filter, good person). Also, somewhere in this forum posted the "Faithful secret" which was exactly like these packs. Vattic's faithful and HiTeen's had actually had work put on these. Also on this list is LITHOS, which is more than just the default faithful, but looks entirely different, but maintaining hard work and the faithful style. I suggest you start over and make a new texture pack without a filter.
As the others have said, don't just upscale textures and run them through a filter. It takes no effort, and makes everything just look blobby, and is guaranteed to cause tiling errors unless done properly.
