Hello ! First of all it's always something amazing to be able to draw. My advice would be to keep practicing everyday, try to just sketch at first (no colors, just a regular pencil and try a lot of shapes, head shapes, body shapes, objects that you see). You will see an amazing improvement from now. Try to draw body parts separately first, then try and combine them to create a full drawing. (body parts or objects). when you've mastered this, I suggest you try different styles, maybe copy some drawing from the internet (always credit the original artist, we all learn by recreating things that are already there). Just try and be really simple at the start, just work on the shapes. I can see that you make little harsh lines when you draw, it's not a full line. Try and draw very clean lines, obviously you can sketch some lines like you're doing now, but always make sure that the result will be clean and linear. (Btw, sorry for the grammar, I'm french !)
