Writing: The Redstone Recruiters(BIG - with redstone icon next to it)
Other details: this isn't that urgent so i don't mind if i have to wait a long time for this! just make this when you have the time and you actually WANT to do this.
i personally think you should finish the realistic one before you get all tangled between the two. Plus i love realistic texture packs - i'm normally the first to diamond!
But its your decision - do what you think is best and what would suit you
