I am really bad with pressure of time to be honest.

I'm sorry about that. It skipped my mind that pressure and some artist don't work well. I personally like artworks that time has been put into. One could see the intrinsic and extrinsic features properly and get the appreciate the artwork better.

I like watching people, trying to find out what they have in their head,

You're very inquisitive I must say, and that's an amazing trait. A superpower like that of professor X (reading minds) would suite you best 😃
