I'd like honesty. Did you copy&paste? Or did you write the codes without any help?
If you copied and pasted, that won't help you at all, and its just a clusterfuck when you update (because then you'll expect to be spoon-fed every single code).
On the other hand, if this is legit.....Update to 1.1, and add a chest xray along with diamond xray. I know its easy to do, but I rely on MCP to do my work<3
