Want to delete file from draft (not submitted or not given Tittle and keyword)

As a side note: Due to a bug in the forum software, we cannot see your attached picture. There is, anyhow, a much better method to use on this forum: use the picture icon or copy/paste the pictures inline.

If I delete files from the Draft section (files not submitted for review), does it affect my contributor account, ranking, reach, or trust score?

Anything that has not been accepted or refused has not yet passed moderation. If it gets refused, it gets refused. That's it. If it gets accepted, and there is an issue with the asset, depending on the type of issue, the asset may be deleted.

In addition if the issue is a violation of the contributor agreement, the account could get blocked. Blocking is immediate if Adobe concludes, that you uploaded assets that are not yours. So upload only assets where you have the full commercial rights. If in doubt, do not submit. 

And be sure to read and understand your contributor agreement. Any violation there may be merciless.

You can delete any files from the "new" and "in review" tabs without any repercussions. Sometimes, I upload a bunch of images that remain in the "new" section until I have time to add titles and keywords, but when I take another look at them closely, I decide they're not stock-worthy after all, so I delete.

Not at all.
