Well, I'm a little late to tell you this, but this is probably the best tekkit texturepacks that I've come across. And believe me, I've been through almost all of them, when I was looking for inspiration.
Sure, there are some things that I just can't agree with, like the amount of noise in the terrain textures. Single blocks can have a lot of details, but highly repetitive blocks need to be low-contrast in my opinion.
But still, it fits the style and the machine blocks look so fantastic, that I am really tempted to imitate parts of the design. (no worries though)
+1 for crazy attention to detail
+1 for handcrafted pixel art
Thanks for the feedback, glad you like it. Can you be more specific regarding noise? I'm not 100% satisfied with a lot of the textures for the dirt and grass, especially.
