[image: s24.postimg.org]mainly comments that are the same as others, there are a few ways to make light dynamics, soft white brush, lighting effects, dodge and burn tools. as artist says soft white brushes are compared to the rest, at getting a hang of. ive done some arrows for the general light thats on the render to show you
as stated the top of your render is chopped, so removing that much of the sig would solve that part
some parts of your render are blurred which looks to be the foreground of your sig, is your focal so most of the time you dont want the focal blurred(some exceptions apply) and in this case he should be in focus
as for the text part i'd try the text there, might look good, could look crap, just to see what its like, and having a we play
overall, pretty good attempt for a first sig, did you follow a tutorial or just go off the cuff and have a wee play around ? either way these are my few points, im quite rusty, and as ive stated before im not the greatest sigmaker, i kind of play about with concepts and see what i can get to look nice but i hope my little paint arrows help.
