Not bad on GFX, might I recommend that you should try to blend the character into the background more or make a more natural lighting to compliment it.
Hey there , you absolutely nailed it on the gfx but there are some few things I think u can improve
Try to blend in the character and the background and even the lightning on the renders and background and you could definitely improve more on lightning other than that it’s amazing and I can definitely see u improve !
