Hi,
I spent about an hour organizing lots of my original doodle concepts into these two pictures. I simply zoomed out of my original concept to make the picture smaller, took a screenshot, then pasted the image into a large psd file > 20 inches width/height.
This was helpful to reduce the amount of single picture images I had, enable to see older developed shapes quickly. I still have lots of original doodle concepts still to be organized and I think I will use this similar technique on 3D models I have made. I think the silhouette techniques would be a nice way of studying/comparing new animals proportions for quick reference.
Hope this was helpful.
cheers,
Nate
