Greetings people! I would like to brag about mine again after quite a long time with drawing. If anyone is interested in a drawing like this or something similar, you can contact me and take a look at mine portfolio.
First of all, not bad. Your lineart is already neat, it doesn’t have any headache-inducing colours (harmony is okay), and it’ll be a nice profile picture.
However, the thing that throws me off is how you shade. I suggest you follow how the shape of the object, not simply putting it where the light source comes from (it looks flat if you don’t). Second of all, i think you should chose different colour for background, as the hoodie’s colour is already dark. Combining it with the dark background, the only thing i could see in first glance is the avatar’s face, making the body assimilate with the background. Try a lighter colour, preferrably desaturated teal.
