Snowman: starting from the very beginning

excelent job with the wolvarine drawing ... going form clint eastwood to that ... well great ... looks great.

One little trick to use when you're drawing something is to flip it over and see it in reverse. It will pop out any little problems that you overlook from seeing it for too long. Works almost all the time!!

Thanks for the comments guys, I appreciate it  .

Decided that faces are really challenging but fun, so I did more. That guy was mid-jump on a snowboard, but the thing was so distorted with snow that I decided to leave the board out.

The drawings are nice.
There's nothing wrong with rendering out things, and these are rather good in that regard I think.
But you might want to focus on lineart aswell. I find it really beneficial to do lots of quick studies, a few pages of the same subject. Repetition is a big part of the learning process. Also try to feel the form ( form = 3D, shape = 2D ), the easiest way to do so I think is to block in loosely and add cross-contours for volume. Try to avoid stiffness, I find that when I copy photographs I go into shape-copying mode ( very 2 dimensional, you need to think trough the form and 'design' it onto the page, going for a more dynamic and sculptural effect. ). A good read about what I mean is here: http://www.conceptart.org/forums/showthread.php?t=160487
For me learning to distinct between drawing with form and drawing shape was an important breaktrough. ( that why I cannot recommend Bridgman's anatomy books enough ) There's nothing wrong with shape copying btw, it's a good way to copy what you see, but there's the danger of turning into human xerox machine. If you want to get good at drawing from imagination form knowledge is important.
Anyway, keep up the good work

I'm going to have to agree with Pieter and say that it would be very good if you were to study form aswell as shapes. Form is much easier to see if you look at something in the real world and not in a photo. This is because your eyes and brain know how to understand depth, perspective and that there is a top, bottom, side, front and back to something just through being alive and seeing. You use this all the time whenever you see how far away something is or know how much space an object takes up in a room. This is where drawing from life if very beneficial because your brain has to learn how to TRANSLATE a 3D FORM onto a 2D SURFACE. If you were to only look at photos there is no TRANSLATION from 3D  to 2D it is just a 2D image being copied to another 2D surface. I would heavily suggest going out to a mall or cafe or bus stop, anywhere populated and just draw people there. Not only will you see crazy looking people but you will be exercising the part of your brain that puts 3D  to 2D.

Not to say it's bad to draw from photos, hell I love drawing from photos!!!! It's really nice having a model that doesn't move and you can just work on making the shapes look good together and figure out good design. Just saying it's good to do BOTH!!! Keep it up and can't wait to see more!

Wow, that cleared up a lot for me, hehe. I guess when I started this whole sketching venture, I didn't really know how to go about it, but what you've suggested makes complete sense for where I want to go with it. And that link will be very valuable for learning sketching form instead of shape, but I still feel like I'll be a little lost as for what I should expect the results to be. With sketching what I see, I know that when it looks similar, then it's complete. I guess these quick studies of form will just look like rough outlines without rendering.

Well, regardless I'm going to give it a shot. Thanks for steering me the right way. And I'll probably keep doing photo referenced sketches just because they're fun, but I'll keep it minimal.

Good stuff man! Mr. Jackman looks spectacular!
