I've been practising but I'm not sure of any means to check my work, can anyone point out if they're any mistakes in this proof?

I have no idea what is “subcomp” in your proof, and how you get 2.
I will not give you the detailed answer, because it looks like homeworks.
The theorem you would like to prove is a conjunction (AND), which means you have to prove both sides: P, and ¬Q.
To prove P, you will have to use reduction to absurdity (from ¬A if you can prove ⊥, then you can prove A), or another of its forms (excluded middle or double negation).
¬Q is easier to prove, just use the ¬ rules.
