portrait speedpaint practice

About 2 hours and a bit speedpaint. Will probably work on it some more and finish it later. I love rougher stuff like this though. Still find it very hard to soft blend in photoshop, probably gonna have to take it to sai to do that.
process is here [link]

if you have any critiques on how I Could've painted it more efficiently in the early stages please feel free to tell me . or just tips in general you know.

My main aim is to be able to paint things and make them look clean and good but without having to spend hours rendering them, i prefer loose sketchy art that isn't overly rendered but am not quite sure how to achieve that.
