Negative space and relationship, proportion and perspective are very difficult for me. My brain seems to throw a mirror image of what I am looking at. Often my angles are completely reversed of the actual subject. Breaking it down to those elements and revising my original drawing is very helpful - to my eye/brain connection ( which is somewhat impaired I think) as well as to the drawing itself.
Practicing copying things upside down is helpful as well. I often draw from memory rather than observation so I have to train my brain to do otherwise.
I remember nature journaling from my college days ( long time ago)- I still have my journal from a Biology Spring break class to the Galapagos - and recognized some of the sites and plants before the naturalist identified the locale. Fun. When I retired, I began to do some informal sketches and notes of creatures and plants. I also applied for a program to become a Master Naturalist- that led to more classes, more outings, volunteer opportunities and the desire to keep a formal journal.
I like the idea of each page having a date, time, location and weather- and using a sketch book- I've never done that- my journals were mostly writing with small sketches in the margins- I like the idea of reversing that. I preferred the painted entries over the sketches but the sketches were very helpful to show the process. my drawing and painting skills could certainly use some work.
I think I will add the surrounding habitat-either by sketch or description and incorporate several of the ideas in the journals shown.
