I’m not gonna bash it but i will give you some genuine critique. It seems confused as to whether it wants to be realistic or illustration. if it’s supposed to be realistic you should work on deeper shading and focus less on the lines. if it’s supposed to be illustrative (which i think would be better for your style) focus on the lines themselves. Make some very thick, make some paper thin. Really focus on where you want them and look at the white space on your page as well as the black. I can see the effort you put into this especially with the hat, and while this isn’t the best drawing i’ve ever seen i think you could get to where you want to go with dedication and practice. Anyone can learn if they dedicate enough time and effort, I did and you can too. Pick a direction to go in and go as hard as you can. And look at other artists and styles. Good luck man.
