I've recently had to ask myself, is visual journaling worth the time? The answer is yes. It has made a huge difference in my creativity but even more so to both my paintings and drawing skills.
Onsite drawing differs from only drawing from a photo. Mostly because of the way our eyes view the vista. A camera lens will turn the photo into a 2-D image...anyway, it does make a difference. My work isn't as flat as it used to me.
The above and below are close ups of the spread. With the weather changing though, I will most likely be working off of photos.
Back to work with me...I've got lots to do...back to glass.
