No worries and thanks for the kind words ^^V. For Zbrush I would say it's not to hard to get into. They have 30 day free trails which will let you see if you like it or not. The good thing is Zbrush has a bunch of "How to" guides via video's on their site which will help a lot. I've been running threw them like mad.
If you want to try 3D I'd say jump in with both feet!
Here's my latest Zbrush sculpt. Whipped this head together in about an hour and a half. Really just exploring how Zbrushes paint tools work...and I love how Zbrush paints.
I wanted to take a minute and talk about getting into Zbrush. I've had people in Real Life and online ask about getting started in 3D via Digital.
Here's my take on it. Just get started. Use Zbrush and dive in. Zbrush is very traditional in the sense of sculpting in Clay. In fact learning Zbrush teaches you how to use Clay (traditional). It also works in the reverse (Clay to Zbrush).
So here it is folks. Don't say you want to learn Zbrush for 3D modeling. Just say I want to sculpt and draw in 3D. Don't worry about polygons or how to box model. Just jump in and create like you would with Clay. If you give an 8 year old clay and say have fun. The 8 year old wont ask questions they will just have fun making some thing. This is what you need to do, go back to your 8 year old self and just have fun making some thing.
Refinement will happen naturally over time as you keep at it. The only thing about Zbrush that is hard (at first) is the UI. For this just go to Zbrushes website and watch the video's on UI. Once you have a small grasp on the UI start having fun.
Now, what are you waiting for just create. Above are my very beginnings in Zbrush. I've made only 3 or 4 sculpts and this is where I'm at. I didn't worry about polygons or worry about if I'm good or not. I just said I want to sculpt and have fun.
If you just channel your 8 year old self, you will have fun. So just create and have fun. These are my tips.
Here's a WIP of my latest sculpt. Currently around 2 and half hours. For those wondering or interested this was made with using only Clay Build Up brush. I'm taking my time this one but it might be done tomorrow night ^^
I'm very inspired by your work and dedication of learning 3D, I do want to learn 3D but first I need to get better at 2D which it's what I love the most.
Keep the good work 
Welcome to the forum,
I look forward to see your progress! 
@motato Thank you for the kind words and I say jump in head first into 3D. You will be surprised at how 3D can really help your 2D drawing skills.
@imphelikz Thank you for the warm welcome. I'll try my best to not disappoint in terms of progress.
Here's the final sculpt. Worked on the anatomy some more and then did subtle changes to break the symmetry to make the character more interesting to look at. I was also able to play around with lightcaps and the movie function inside of zbrush to make a turntable. Overall I think it came out nice but I have to say I need to work on modeling ears.

Posting a little update. I've been sculpting everyday but nothing worth finishing sadly. So today I wanted to go back to basics and just work on shapes. So I wanted to attempt a new work flow with making the head and torso with a start on the lower half of the body. This was made with going with 3 sphere's and trying to think more traditional clay than digital if that makes sense.
This is all I could get done today on my sci fi animal. This all started out as just a sphere in which I used the move tool to find a shape I thought looked interesting. From there it's just a lot of claybuild up, pinch, and standard brush. I'll be adding a body and painting the piece as I think it looks pretty cool. Below is a non-shaded screen shot and a BPR lite screen shot. Crits and comments always welcome.
