Hmm im glad i get to rate your sigs :P
First of avatar- hmm maybe 6/10, its kinda plain (im not one to talk xD) but the lack of colour i suppose bugs me, its basically 3 colours so 6
the signature though
now its easy to say 10/10 but weres the fun in that
obviously a 10. the second image the one by yourself is so awsome i love it, its truly a great image, the colours blend well and the atmosphere is truly great.
the other image, well the woman kinda creeps me out if im honest :P but the use of colour is more than anything to make up for, its actually such a great use of colour im behond jealous
