/ic/ - Artwork/Critique

Hello anons, I want to comment on a situation of mine.
I have been improving my drawings (I still have a lot to improve but I am certainly not like at the beginning, I am 6 months old as of tomorrow)
And I feel... that I'm stagnating, I haven't drawn something that I like or that I consider decently good since Friday.
Any comments or advice on how to break this mental or practical limitation that I have, I will put a semi-timeline of my drawings. If they tell me the names of the books, it would be great. I have used several of anatomy but perhaps I use very complex ones.
My goal is to be an independent illustrator and earn a little extra money (I say this because when studying this I think you need to have set goals)
Sorry if I post it here in general anime/manga style but it's the style I more or less want to achieve.
And as a last thing, excuse my autistic English, it is not my main language and the people of my language do not seek to improve, only to trace.
