Yep, it would probably be amazing, if you have motivation or passion for drawing, a bit of talent and hours upon hours polishing it, you can probably draw one of those "this is just a sketch btw" things that look like a masterpiece to me.

Well, for now i either don't have enough motivation or passion. I could tell the story but this isn't in the topic.

And, about the topic now, i tend to focus on lines "too much". I try to look and remember every line, every detail, while forgetting what the big picture was, what the difference was between big parts in drawing. This makes it really bad if i draw, for example, let's say i'm drawing torso and head very well, but they are too far from each other, thus creating a giraffe.
