Nice! I definitely concur on the bottom one being better.
If you did it again it might be worth lightening the grey on the clouds of smoke so they stand out from the car and its shadow
That’s a great idea. Thank you! How would I isolate that area to make only it lighter?
Change the color in your graphics program and re-upload the file. When you go to engrave they should pop up as separate elements to the overall image. Then you can assign a lower power setting for them.
