Thanks any suggestion to improve the 'i'?

Logo is for an IT company.
I'm not creating whole set of typeface. Just these letters

*actually I didn't tweak or inspired by sansation. I followed my sketch and my eyes. Maybe there is sansation in my subconscious mind.

more rounded 'o', added ligatures and extended lower end 'c'

You probably need to resolve exactly how someone should read this. I had a bit of a time parsing the letters into something pronounceable. If I.T. is an acronym for information technology, then maybe distinguish it a bit more. I am not too familiar with that field, but the name doesn't immediately sound like a brand - more like the name of a sector of that industry.

/c/ feels too wide - maybe try something more like your original sketch.
The latest /o/ is nicely improved.
The thinking behind the latest changes to /it/ is good but the execution doesn't work.
/s/ leans backward and feels a bit too imprecise for what I am inferring that you are trying to communicate.

The old "e" was the best thing about it. :-(

The flag makes me think of golf. Is it meant to be a play icon? Maybe try your old /m/ in there too? The initial /it/ seems too dark almost becoming an icon.

What I meant was that /it/ is becoming a little abstracted from letters. It is moving toward becoming a symbol, something like π. The boldness, ligature, and flag contribute to that. Whether this is a good thing or not is a question you will have to answer yourself, but I was assuming based on your initial sketches that it should be read as a phrase: "I.T. Semiotics".
