Hey everyone, I am brand new to affinity designer/ illustrator and all of that sort of thing. I am playing around with the pen tool since I had always had a hard time with it in the past, but I finally decided to try to learn it. I was tracing my thumb and for some odd reason, when I went to close this shape and then fill it, it is not filling clean and nicely. I am not sure what is causing this and I need help understanding. Thank you for the time you take to read this and help me gain more knowledge and understand.
See below the file I am currently working on and a screen capture of the problem area as well. Thank y'all!
