Sorry to hear bout your mouse, A Razer deathadder is a nice mouse, I love mine =p
But really what I came here to point out is that the mycelium has to much of a bright purple/pink to it. maybe darken it so it looks like a faded purple. also the enchanting table doesn't go together. navy blue book, light blue trim with black base doesn't look very good. id say keep the black and orange look or the navy blue. Also this doesn't need to be changed but It would be cool if you took a look at the powered rails when powered there is a little to much yellow, maybe make it looks a little more like unpowered powered rails.
What I really like are the redstone repeaters, beds, and torches. (beds needs an icon update tho cus its still red)
