I too am working on coloring my projects too. I like how much better they stand out when posted on the wall. I do not expect to ever become a true artist but I am going to continue to paint and try to learn. If that is your desire, take the remarks that are all intended to help and continue to paint and learn to make it realistic as you can. Look at your results and see what you might do a little differently next time. That is how you achieve your desires. It is just like scrolling, when you start out, it is quite difficult and your mistakes can be way off what you were hoping for but with time it becomes easier and more satisfying.
