Text could use some work its too off to the side and dosnt blend with the render make so it belongs there or dont ass text at all/
there seems to be know real focal point and it seems very lq
Lighting isnt that great either your whole sig is the same brightness if that makes sense you need to make something(the render) stand out more than other
Just keep practicing and using tuts all you can do now is improve
