I have experience in blender, but I have never made a GFX, I really wanted to see how to make one so… I did.
Here is the final image.
Lots of editing as you can see, and the earth is a little deep-fried lol.
Unedited image, nothing special to see here.
Its good, i like the sleek look of the character but, (excuse my nerd talk) in space there isnt really much light, and your character looks pretty bright as if its on earth. It just looks awkward for me i guess. A suggestion for a next GFX, focus on lighting, as light is important, but not in space 
Hey, its your first GFX, so good job!
Yeah I understand what you mean, I think it would look a lot better if I made it a lot darker. I’ll keep that in mind as I think I’m going to keep making space GFX`s.
Well not took dark, you want to see the character, just heres an example
Its not too dark, but it has a good amount of shadow casted on the body.
Its hard to explain but i hope you understand
yeah i understand what i did wrong with the lighting, not too dark but like, ur still able to see that a person is in space
For your first gfx, it looks really good to be honest! Maybe you could make it darker though it looks too bright.
