Hi Zed, just keep practicing the F chord. I do not remember how hard was for me doing barre chords the first time but now that I’ve been revisiting some and relearning others I am aware of the challenges. But with regular practice and patience it will improve. In my approach for practice, once I am satisfied with my progress with most of the content of a level (Classic Beginner Course) I start to replace it with content of the next level although I may keep a few practice items of the current and even previous levels active for further improvement.
That electric looks very small!!
