Sighing, Nodding & Clichés

Now, 60K+ into my first draft, I am more and more aware of the repetitive phrases and clichés and just general rubbishness of using the same words and gesture over and over again. For example, my people nod a lot, sigh a lot. They also glare a lot, and narrow their eyes a lot. As I write more, when these words come up, I am aware of them but I still write them and carry on because I know that if I stop to think of a better way to write that sentence, I will start editing as I write, and that would then hinder the writing. The frustrating part is that I am aware of that, and I know I have all that to fix when I do begin the edit. On the other hand, the fact that I notice these things now, is a good thing because at least it means that I am spotting some of the things that need improving. Another thing distinctly missing in my first draft is description. I have known this for a while now that I am a dialogue heavy writer. Dialogue comes much easier to me than description, so much so that often my first draft lack majority of description. This time, it's no different. There are very few scenes where I have taken the time to describe the surroundings etc. So that is something that will need to be added with the edit. There is a reason why I am not worrying about it now. I feel that first draft should come from instinct. So as I write, I just get on with what comes naturally to me. If I happen to think of description, I put it in, but if I move the scene ahead without describing things, then I let it be. Because I feel that thinking about that would be another thing that would slow the writing down and also make me worry about what I should put in, how much, how to describe it etc. So if it's needed, it can be added later. So far I have got my outline method sussed, but editing method is still something I need to work on. Haven't found my perfect match yet. I am hoping that this first draft will be in far better condition than any of my previous first drafts, which hopefully in turn should make finding an editing method a less frustrating experience. How do you feel about your first drafts? Are you notices holes and faults? Or do you think you are sailing on high seas?
