There are "some" Photoshop wannabes. I still haven't found any program on Linux that can give me anywhere close to the same ease of use and powerful tools that Photoshop has. The example you provided sounds like you want to use Illustrator for your use case anyway.

Pixelmator Pro is very close... but Mac only, still. Image editing on Linux is rough.

Have you tried Affinity?
