You did a good job, you can improve it even more with a slight lighting as you did in the head
Not Bad For First time,Good job
For a first time, it’s not bad. Maybe invest some time in watching a few tutorials such as (rigs lighting editing and posing) it will defiantly help you learn in the future. Keep up the great work!!
Looks good for your first time! Nice job! 
Okay, so it’s editing lighting with “Soften Portrait” and adding a font, with drop shadow on the text, and I’d assume you’re using Paint Dot Net.
We all start somewhere man.
I’d recommend looking up tutorials on how to make more GFX though YouTube and getting into Blender to start learning unique stuff like lighting, arm bendending and such to improve it a lot more.
Goodluck on your future stuff man!
