The Art of Improvement

I have never been to good at drawing. Especially when it comes to drawing people. Through out most of my life I've avoided the drawing aspect of art and just stuck to painting. The older I got the more I realized the fact that starting out I wasn't much of a painter either. I had a bit of natural talent but that natural talent needed to be sculpted. The same concept applies to my drawing I believe. I've practiced a lot for the last couple years and feel I've learned some new techniques that helped improve the quality of my deawings. However, to broaden my horizons, I'd love to learn some more techniques and ideas to better my drawings. If anyone has any ideas or critiques to help me with my process it would be deeply appreciated it.
