Hi Zoller!
Congrats on starting to seriously draw!! Its a really exciting time because you will see serious progress in only a few weeks/months! You are already good at proportions. The placement of everything is good! And yea, you did realize that shadows are the next big area to work on. Be bolder! Like, a lot bolder. Don't use HB pencils or lighter, use 3Bs or darker to loose the fear of going too dark. Dark shadows will really help create the depth and shape you are missing and looking for.
If you can't figure out where to place the shadows you can try two things. First: stare at the picture/thing youre trying to replicate through super squinted eyes. This way you will see which parts stand out in darkness/lightness. Try drawing what you see with only two values (

Second: Take some drawings that youve done already (like the one you showed here) and draw a 3d grid over it (like this: https://adventuresintheartofgames.wordpress.com/wp-content/uploads/2015/04/screenshot-2015-04-26-11-33-38.png) and think about where the lightsource is. The grid will help you better place the shadows because you can see the "hills and valleys" of the form.
Good luck!! I believe in you!
LG, Mikay
