[NASM] OS Critique please.

[Goalatio]

This is my OS that I've been working on for almost 3 months now (not all at once.. in periods of a few days each time).
Would anyone skilled in NASM mind looking at parts of it and give me their opinion on my code?

Note that there are many files; I'll do my best to organize it all right here.
Anybody can use any of this code as long as my name is in the credits. :)

Boot.asm

Kernel.asm
Includes.asm

Thanks for taking a look. I was a bit hesitant on giving this out, but finally gave in since I haven't touched it in so long. Enjoy :)

Links deleted because some idiot tried to take credit for everything. Thanks for the few people who actually tried to give me some tips. I'm sorry that it had to be ruined for everyone else.

I have had a look at the videos, looks like you did a good job. ;)

You could always post a link to a disk image (.iso), then the actual OS could be tested and reviewed.

^^ Just a suggestion.
