Woah, the difference is pretty sharp, with shading and all. I almost thought that you had someone else draw for you again,

its fabulous

I love how that "draw it again" thing was only 5 days apart. Other people usually wait years.

Set the option "stabilizer" high combine with "pen" & large canvas can give u the best outline art.

There are many ways to do clean lineart, that's not necessarily the best one, it comes down to personal preference and efficiency.
Good redraw though, keep an eye on your line weight though, making your lines thin in some places and thick in others can be good if you keep composition in mind, but the way you've got it kinda looks strange.
Also, your clothing folds are kinda off, I can redline it if you ask, but the way you've got it ignores gravity and how clothes would normally drape.
Lastly, you kinda need to work on your muscular anatomy. Specifically her arms and her core are bothering me, but it would be good to practice in general, along with some gesture drawing so your poses loosen up some, right now they're pretty stiff and lack expression

I always prefer thick line for cartoon arts.
Sure there are a lot to learn, especially anatomy, but better now than never.
U can redline anything bother u, details will be good

I did a paintover here to show you where you messed up.

Things to look for include:

Ridiculously large/puffy hair
Zero understanding of arms or stomach
Eyes that belong to dead people
Bad understanding of clothing folds
Proportion issues

I also frown upon your linework, but half of that is my preference. The other half is how messily you've done it. No line variation or tapering at all. Bad.

You can see I've set the light source proper, and made everything respect that light source. The way you do hair is simply bad. You're just making stokes of lighter colours to indicate bits of hair. I've brushed it all down to clumps of hair then made small individual strokes. The folds on the trousers have been changed. They should only start from two places. Hanging from the crotch area, and clumping around the bottom due to gravity.

Really, what you need to do most is to study anatomy and get a good grasp of form. Remember that the surface is lit up the most when it is perpendicular to the direction of light, and shade your drawing from there.

Quote from C3WhiteRose

Anyway ur eyes drawing makes her less of a "cunning, careless, enjoy pissing off others" character to me

That's how Lobo normally draws eyes, then again it can be argued that your eyes makes her look like someone told her that she's evicted.

You're faring better than the other stack of artists graced by his presence.

Oh my god you go girl! Its awesome!

@Guardian:
I will continue on practicing after RHG5. A guider will be good.

Yeah, Lobotomizer pretty much nailed it down XD I think you could have gotten the cunning attitude across a lot better, though, if you changed her expression! Expressions can help explain a lot about the character that you can't just get across with the eyes, which is what I felt like you might have been trying to do. When I think of cunning, I think of intense eyes with a smirk or grin, and maybe even slightly furrowed eyebrows or a raised eyebrow. Remember to think about exactly how a character might get their personality across with their whole face the next time you draw!

I tried something, look quite fun

Yooooo what did you use to make that?. It's so cool!!.
