im gonna have to agree with everyone else about the brown that color is very dull and is hard to work with unless u know wat ur doin
as for the smoke effects its kinda a fail lol its not well used and i didnt even know that was smoke i thought it was like ghosts lol so try to smudge it next time it will give u that effect u wanted
then for the text i think its too big and rlly bad u should try to lower the size of it and put it near ur focal cuz the txts draw the attention away for ur focal
the borders r way too big try making it smaller
also i dont know if its me but i see a green dot on the one of the wheels and once i saw that thats like the only thing that stands out to me lol
i give the sig a 2/5 u should go look at some
TUTS to get better
