I'm not an artist in the slightest but I do have multiple attempts at learning to draw with various sources so have an idea on the basics that I myself can't apply very well. It looks good but I will ask if behind the face, did you deconstruct and then construct the face again, or just try to copy it as it it?
Also I wouldn't copy another image if you can help it, use it as a reference but make it your own.
After seeing this thread, I decided to start once again my quest in learning to draw. So firstly I'd say if you haven't considered videos/courses/tutorials before, take a good look at Drawabox, something that was born from Reddit I believe https://www.reddit.com/r/ArtFundamentals/

Over the years I've also watched a guy called Jazza (formally DrawWithJazza) on YouTube, his channel has changed now from the traditional art, so I don't watch it much anymore. I've purchased some of this material which I'll share with you, you might find the anatomy and faces books useful. There is also an app in the folder which is a games app. It gives you ideas and one of the best features of the app will tell you something random to draw.
