lol well the only reason i had it bigger is coz when you have it smaller like it is the crowd isnt as noticable and it doesnt look like a crowd it looks like a brush or something blurred heaps..
Nearly all my sigs are 400x150 or 500x150 and sometimes a little bit bigger depending on what the cut/picture ive got.. hate gradients so hardly use them.. im over renders and only use them on the odd ocasion.. if you mean dont use too many brushes about this sig, i didnt use any at all, but if you mean for others than yea..
I just meant the tips in general. Always use a gradient map, 100% of top designers use gradient maps and they are so effective. I use 3-4 gradient maps in my sigs and it makes a hell of a difference.
