I like em, text could be a bit smaller on the mario one, also mario is a little to bright for that sig and you put a little more then necessary black spatter brushes on it green doesnt go well with the mario in my opinion, on the top sig maybe take the black burn marks on it and put a deep blue white gradiant map on it instead. the flash animation is quite impressive on your sigs.
also what are you applying for? freelancer, fulltime.
what experiance do you have, and what programs you use.
