I’m here to tell you, “Hey…it’s ok.*” Reverse engineering the work of the masters is the concept of education in a nutshell. Seeing something and finding your own way to reproduce it is a great way to learn. As you go through the process, something will click, and some little technique will get tucked away in your brain, ready to be called upon as you find your own creative way.
But there is a difference between this method of learning-by-reproduction and being influenced and inspired by other’s artwork. Learning how to use inspiration to generate your own ideas is a learned skill in of itself – an important one at that! Having influences is implicit in creative work, and your style is born from everything that you are exposed to — your experiences AND your influences. Your eventual “artistic style” that develops will be comprised of everything you’ve tried and practiced, mixed with a little brain magic, to create something all your own.
*Don’t get me wrong here: plagiarism is 100% not ok, and you should never reproduce another artist’s work and pass it off as your original work. Learn from it, leave it in your private sketchbook, and move on. I’d advise against sharing this type of work online (even if you’re only sharing your learning process) without permission from the artist.
