This remind's me of slaves first tags ha
Few things i like are: The gold color matches the render realy good. And i love how you didnt place the render in the midlle of the signature (wich most of us do). I also like what u did with the sword and the c4d
Few things that need to be improved are: U got to add some depth in here a good way to do it is using the blur tool and sharpen filter . like ish said when u size down the render hold shift. this will make the render equal . Next time try to brin in more color's I love the gold color but it gets borin if there is to much of it in there.
Cant wait to see future work of you
