first of all the background and then font kinda clash on the red sig... it works well but there is too much going on... i like the first one its original, the cutting is good and the background goes well with the rest of the sig... as for the last one... personally i dont like borders abd youve got two so that makes it worse it makes the sig look tacky... i dont really like animation but it works well with the sig...

the one peice of advice id give you is to carry on making them and post em up on here
