It’s good now and then to look back at one’s work and see what was then important and to compare it to one’s art of today.
Experience is a great teacher, but so is confidence and self-belief. I always believe that the next drawing I do will be the best I have ever done. This is not always the case, but it’s good to have high expectations as this makes one try harder.
Complacency in art is a danger that must be avoided. Do your research, plan your work, enjoy the creative process and be rewarded with the product!
