There's stuff to learn about drawing but mostly it's just about putting pencil to paper on a regular basis. That's the most important part. Take a figure drawing class and do a bunch of pictures of naked people so you have an idea of how basically to render lighting and whatnot on paper, and then just keep doing it until you get good.
Once you start making pictures that are close to what are in your head, get people to look at them and tell you what's wrong with them, because there's almost always something wrong with them, and then fix the problems. The point is that it's all about drawing; you can't learn to draw without doing a shitload of it, and any drawing you do makes you better. So my recommendation is that you just do that, jump on it.

Hi, I'm also starting guro drawings series.

I recommend you to read and study anatomy books. Everything related to medicine is very useful, you have to learn at least some basic things about the human body and its functions to make your pictures look realistic and not just some anger-mood-doodles. (like for example, my picture. Yes, sir, I drew that a year ago in a very angsty moment, with no references. The results are terrible if you're looking for a decent gore image)

Anyways,practice is always the best way to be succesful.
I have a drawing magazine with a "Gore Special" tutorial, I can upload it here, but it's all in spanish ( my language, btw, sorry if my English sometimes is not good). If you really want it and feel it can be useful for all the people here, I can translate it and share here.

Have a nice time drawing~

Practice on a more than regularly basis combined with hard work, determination and will power is going to be what gets you to where you want to be. It sounds pretty clique because these are all things you need and if you don't put the effort in you won't get anywhere, don't count on the mystical factor "talent" to get you anywhere.

You definitely want to study anatomy. Understanding bone and muscle structure is key to being able to pose models realistically. Proportions specifically you'll also want to look at.

No one give love to the creep until it stops the asking like that

I am a noob and do art casually as a hobby, so my opinions might not be helpful,
i think that to draw gore stuff u can refer to medical anatomy of human, those pics or photos with cross section of the body, organs...etc
i think coloring is important if u want to emphasize the bloodyness too.
i forgot to mention, guro doesnt necessary to be bloody. (correct me if im wrong.....)
i believe these above can give u a direction to start on, but cant really "teach" u how to do it lol, u need to practice yourselves to get it.

>>11420 I totally agree!!

See what happens when you're a new guro drawfag and have no references?!
Please guys, study a little anatomy, don't make epic fails like me
