Get a better texture pack the current one sucks
It's my own creation and it's a work in progress. Why not actually suggest how I can improve it?
On an unrelated note, I want to get my texture pack to a decent level of okayness before continuing the adventure. If anyone has any suggestions, please PM them to me.

Top to bottom:
Stone
Cobblestone
Mossy Cobblestone
Bedrock
(in hand) Obsidian

Obsidian crosscut through the other four
I feel okay with stone and bedrock, but cobblestone is a little to close to stone for my liking and the mossy cobblestone just sucks. As for the obsidian, I somehow accidentally turned it into an 'ore', which I don't really like.
Even though I would prefer to wait until I feel the texture pack looks better to continue the adventure, I'm going to continue it anyway.

You go around to the right. You're almost back to the entrance when -- OH GOD CREEPER!
(I really am seeing these creepers, it's just hard to hit the Prnt Scrn button while they're in my line of sight.)
