Ok, so let's get the good sketch out of the way first (or at least I think it is at the time of posting)..
I am suffering form a severe case of "is this crap...maybe it's really crap and I just don't see it". I also have reason to think like that..because a lot of times I look at a drawing after I'm done and I see how wrong it is...sometimes, it's proportions, sometimes it's the pose, sometimes it's shape design..and sometimes it's all of the above :P
But you know, I'm not getting paid to draw in my spare time, so as long as I enjoy the process, I'm happy. I honestly just like moving line across surface...if a good drawing shows up at the end, it's a nice extra :) Anyway, below is a wolverine sketch...scroll down if you want to see how it came to be,
The thing about drawing 'realistic' is that you can't get away with much, it's either right or it's not...
