This is the official topic for the Cold'Molten Texture Pack. If you're here in the early dev, you're a good person.
Also, there is nothing interesting in this texture pack currently. Please be patient with this pack, and please do not critique until actual textures are made. Thank you.

This looks way too much like the default. I would have no problem with a minimal first post like this if the designs were original, but the only changes you've made are ones that anyone could do in 10 seconds with a Colorize tool and a fuzzy select. You really should wait until you have a little more to go posting.
