Hello
I also just joined like 2 Days ago i finished 2 courses already
https://cgcookie.com/course/learn-the-blender-basics
and then
https://cgcookie.com/course/mesh-modeling-fundamentals
the exercise first was a struggle but i am getting comfortabler already.
Of course to say i can make this in blender, i think it depends on what and how far
you proceeded with tutorials courses and flows (the exercises are great to do for practicing).
As for now i think i could model simple things like a house table maybe but i wont be able to make a human (or at least not a decent one (maybe a stickman xD)
I did spended quit a lot of time watching the video’s and model along with it (even if he just explained certain tools.
That way you get to use them already a few times before you get into the exercise .
At least for me this method works well to learn things better or faster
About what kinds of models are you thinking when you feel like i need to watch more tutorials or courses ?
