Let me just put out there: I am a big advocate of letting your art be finished when it's finished. You can't go back and redraw every single drawing you've ever done everytime your style changes or improves. I say this because I have a compulsive desire to REDO everything I've ever posted, especially when I go back and look at my old work and cringe.
However, sometimes taking long breaks in between "finishing" a composition pays off in significant ways, especially when you're like me and you archive all your .PSD files from years past.
I can demonstrate this better with the images below.
So I drew this piece back in April 2018. I just wanted to draw an angry red girl with dynamic movement, probably about to punch a nazi, focusing on the color palette and texture of the drawing. I posted it, and didn't think about it for another month.
One Month Later
Then in May 2018, I looked back at the original piece and thought "hmm. That coloring is odd. I'm going to fix that." And in the process I tried fixing the anatomy of that pulled back fist, and added more detail to the face to convey a clearer expression. At this point, also, I was working on my personal portfolio website, and I wanted to just wrap up these edits so that I could have a nice, vibrant hero image for my homepage.
However, Another Month Later
DID YOU KNOW THAT USING PHOTO REFERENCES CAN SIGNIFICANTLY IMPROVE YOUR ANATOMY? I said I tried to fix the anatomy of the raised fist back in May - it is now June 2018, and I took a picture of my friend pulling their fist back, and used that to properly fix the anatomy. That, with changing the shading on the shirt, and fixing small mistakes around the face and hair, altogether allowed me to finally finish the composition.
And these aren't redraws - this is going back to the same .PSD file and changing individual layers without having to start a whole new canvas all over again. It would've taken a lot less time had I named each of the layers something distinguishable, and not used the Auto-Select layer tool to figure out "what the HELL is that one line I want to get rid of it oh it's on Layer 91 son of a-" BUT. My point still stands.
It's okay to fix your shit! And honestly, if you're in somewhat of a creative rut right now, I highly recommend it.
