First GFX I’ve ever made. I would like to get some tips on making and improving this kind of stuff as well as some overall feedback.
That’s a good first GFX!
I’d suggest learning the basics of Blender and finding a good photo editing software to edit your GFXs (photopea is free but it’s a good alternative if you can’t get Photoshop or Affinity!) There are good youtube starter tutorials on getting Blender set up to create GFXs.
I’d also suggest having a more dynamic pose and making the character in a scene rather than making it look like it’s floating on an image the next GFX you make! And using light is a good idea to enhance your GFXs even further!
You have a lot of potential, so keep it up!
