I just tried drawing hentai today, and while I'm surprised that it came out even somewhat decently, I'm wondering how I could improve the quality of future artwork. Any suggestions? Here are the 2 drawings I made, each using a reference:
Pick up the Loomis books, they're free and very good beginner books. I wouldn't suggest picking up the How to Draw Manga/Anime series right now. Even though i own a copy they're largely teaching you how to draw an exaggerated form. Which is useful when you're trying to work out a style. But right now you need to focus on straight structure. These pictures show a lack of figure knowledge. You're clearly trying to get the human form right, so i applaud not resorting to some distorted cartoony form.

When we draw our brains tries to pull up as much information as we have on the subject matter. In this case it's a human female, most people have a very basic knowledge of the human figure. We instinctively know all humans have two arms, two legs, a torso and a head. But proportion and detailed structure aren't usually common knowledge, the average person doesn't need to be that observant. Artists need strong Anatomy & Gesture knowledge to pull off a convincing human figure.
There's a number of other things that can be improved here, but i'd focus on Anatomy for the time being. It's worth picking up Villipu for it's segment on gesture, i can send his book to you over Skype if you want to give me your contacts. I'll list off the other things just for future reference. The line weight is a little wonky, use hard edge lines to draw focus to a location. Meanwhile use soft lines to bring something out of focus. In the drawing of the pig tails girl the right pig tail is falling behind her shoulder. Because it's further away from the viewer you can bring it out of focus with a soft-edge.
In your second drawing you drew a full outline of the hair and then shaded it in with a light tone of gray. Our eyes will always follow the dark lines, so the hair will inevitably look like one giant clump of hair even if you spend a lot of time on the details. The easiest way to do this is to avoid drawing the entire clump of hair as a whole. Instead draw the locks of the hair.
I'll leave the anatomy out since you can read it up in books. However when drawing a human figure start with basic shaping before you set down a hard line. The first pass won't always be the best pass. Oval for the torso etc. This also gives you time to work out where you want the light source to come from. In your second picture the light source seems to be coming from above and slightly to the front of the girls. Going based off the shadow being casted on her neck. From the angle the Breasts will cast a shadow onto the chest. And the breasts themselves will have a gradation of shadow on the lower half because they're protruding outward in the shape of a ball. The belly as well will have a small half tone shadow because it's rounded. There's other half tones as well but those are the big ones i'm listing off.
Lastly the face needs some work as well, but i'd leave that for after anatomy and gesture. You seem to have used the Green Lantern symbol for the eyes :)
