If so how do i execute because after looking at pictures I don't notice that in toriyama's style, i could be mistaken though.
It's true, they are called line weights and they can be used for various reasons. This isn't something limited to Toriyama by the way, it's a technique that most artists who use linework know how to do.

Notice how the close up shot of Gohan has very thick lines, whereas the full body shots of the other characters have thinner lines. Because we can see the entire body of those characters, this would imply the camera is farther away from them. I don't recommend going to extremes with this on a single character unless there is some exaggerated foreshortening going on, It's best to use this for more then one object in the scene to show off their varying distance from the camera. Of course you can add your own flavor to a piece and do what looks best to you, notice the really thick lines on the major shapes of Gohan's hair and face? I assume Toriyama purposely did this to pop them out of the picture and draw your attention to the focal point, Gohan's head.
Another way to use line weights is to make the lines on a character slightly thicker where there is going to be shadow, likewise they'd be thinner where there is light. You can see a good example of this on the pants of Gotenks.
By the way, you might not have noticed this if you were looking up pictures from anime. This is because there are thousands of frames that have to be inked in anime, it'd be pretty ridiculous to expect all the frames to get this treatment(although you do usually see a difference for closeups as stated earlier). You'll mostly only see this much care in the lines if you look at finished illustrations.
As for critique on your picture, I'd say you did a pretty nice job on the pose. It looks like you're having a bit of trouble with the structure of the head and hair though so watch out for that. Good job with your foreshortening though, it's easy to tell his left leg is close to the camera and his right hand is farther back.
