Your skills aren't that bad, actually. Try not to put yourself down too much.
I'd recommend choosing whether you want realism or a cartoony style. Or, you could always do a blend, like I do, or in anime! But I'm not a pro, so you do what you like. lol
Anyway, developing a style that appeals to you and is easier for you to do will GREATLY help make drawing more fun and as you develop your style, your skills will grow along with that.
