I remember making a panel of soldiers holding Shields together while firing their guns at their enemies way back in 2020. Now looking at it compare to my new panel, I forgot how much I progressed. Here they are.
Before 2020:

After 2023:

While drawing this image, I learn a few things about how to do better than my previous one. Sometimes I have to concede on trying to do everything myself because I realize that no matter how hard I try, I won't be able to do better than the other options that would help me improve.
Like the dust, light, and clouds are Photoshop brushes.
The texture of the soldiers are vectors I have to download from Shutterstock and colorize them to the color I want them to be.
This also includes the vectored bullet shots, and bullet dashes I downloaded because they're better than my own, just look at the previous image and compare them. All I have to do is change its colors and set the blending mode for the layer.
Sooner or later, I will have to model the guns and other types of weapons in 3D and make them look 2D afterward once I started my Sci-Fi Comic.
If any of you are wondering, yes I worked as a graphic designer, 2D animator, and 3D modeler at a company called Ghaliah. That explains how I improvise my comic art styles and considering I sometimes get overworked with my job I have to find a way to finish my pages quicker every less than 10 days most of which are 4-5 hours a day during working days.
What about you? You can show me your before and after work and explain how you improvise. It doesn't have to only be a rework but also artworks that looks similar to the old ones.
