Not to be picky or anything, but Rocket's post seemed a bit rushed and didn't describe his character in any way, merely rehashing what had already been said. I would suggest you go into detail about his character for a short bit through a minor action or reaction, and then put fuckloads of compound, complex, and other sentences in there instead of having run-ons. Try and pad it with unnecessary details with a lot of separate sentences that actually mean important things.
Sorry, but as a very poor writer, I like to force my self-criticisms on others. And take all advice with a few grains of salt: personal style is something everybody should encourage.
