starting a drawing with circle, ovals, overall shape of composition

Hello,

I would be greateful for any feedback

maybe u could have called me gifted as a child, but i am old now(30) and mediocare at best, never put structire to my practice, i used to only paracice sporadically and never progressed.

I think i need to unlearn a lot of bad habits.

one of them is that i dont do "blocking" i just put a pen/pencil to the paper and draw lines. And when i try and start drawing with what i think is the overall shape of the thing i draw, it turnes out much worse and it flustrates the heck out of me. ;( , lol.

my line work is bad too. Not to mention the shading, but i dont do much of it in these quick sketches.

I guess i just need sb to tell me that my drawings need to go worse before they get better.

below i will try to attach few of my sketches, the "old way" , without the blocking, (as the results with blocking are too embarassing, it takes me tons of time to draw anything when i try to block. In contrast, when i draw outlines, i just do it quickly on instict)
have a lovely day , Chestnut
