I'm embarrassed to show my work to others
Also, a good artist self-deprecating their own work sounds exactly like that skinny friend who's always complaining about how fat they are: infuriating.
The importance of self-confidence and having a "style"
Next in order of importance is to keep drawing a lot and keep putting your work out there for people to see.
If possible, keep drawing in the same genre, and when it comes to the content, make sure it doesn't range so much that it goes full-circle (like the work by Mr. Big Mikio Igarashi or the song Suirenka by Shonan No Kaze). Try to keep your temperature constant even among different topics.
If you don't show your work because you're too embarrassed, you won't get better, you won't get any views, and you won't find that confidence you're looking for. So keep drawing and posting your art.
