If you need tutorials try googling Andrew Loomis, his work was amazing and it’s free. Try finding his pdf books or actual images. He guides you through everything. If you’re a begginner, try ‘Fun With A Pencil’ by Andrew Loomis. And don’t get discouraged. Everyone is a born artist, we all draw as children, but most of us put art aside as we grow older, since we don’t practice our skills, we don’t improve. Thats the only barrier. Stick with it, in a few years you’ll surprise yourself with how good you can get.

Look up drawing feet and hands tutorial on YouTube and you’ll probably find some good ones there :)

Ah yes, the feet and hands, my great weakness :-p  
Do you know any tutorials for that kind of thing?

@Ansi-Marelina  
You can, but try working better on the figures body parts themselves that includes feet and hands :P

Thanks again for responding, and something I’m wondering- can I keep my art style simplistic and still have it look good?

Again, use more depth and asking for computer paper to show or pop out your drawings
 
Drawing human figures is a pain in the buttocks and it’s for everyone including me :P
 
Try looking up videos on how to draw human figures or look up bases that you can take inspiration from :)
 
And use a 2 liter pencil or any good, non-breaking mechanical ones that can help darken your lines
 
Also try working on the face more and you’ll be in getting your art style up in going sooner or later
