some CnC:
Text in the corner - never do that
Render is cool - but uve warped it?
the render isnt well blended IMO - the lighting is the only thing thats helped blend it but its seemed to lower the quality
so yeah a render on a bg for the most part
Also - just quick - it seems like the c4d is just pasted there? i think uve layered it behind as well but its just not clean and the flow is disturbed because of it
not bad tho, keep on trying and you will improve
