Inkscape: a free and open source vector graphics creation tool.
https://inkscape.org/
I'm well, not great at art, inkscape has been fairly easy to pick up and start using and producing polished looking content. I've found it easier to start making vector graphics because of the use of basic shapes without having to worry about scale and level of detail since I can output at any piece of art at any resolution. It's fairly easy to get into but there is also lot's of features and depth so I think it can be used to make professional stuff without being overwhelming like Blender or Photoshop.
Also a bonus of vector graphics is it's super easy to make adjustments since your dealing with objects you can manipulate, not pixels you edit, so you never like ruin your project. Obviously a style choice but for bad artists like me, it's something.
There are some useful tutorials available too. Just look up inkscape tutorial on youtube.
Here is a cool doritos salad man I made. Don't steal him, or if you do he has to say the line "Hay everybody, I'm just tagging in here for a short snack, see ya'll next time!"
