Is it one of your first models?
If yes, it’s fine but you should spend more time on defining the base shapes.
It look like you moved strict to the details, forgeting about shapes that define the character.
Good start but there is still much to learn 
Thank you very much for your opinion nebular
You are right there is always something to learn
also in the simplicity is sometimes a model loading too original idea is lost, and in this case what I wanted, will continue to work anyway, thanks a hug
