in order of creation I just started making sigs yesterday and I cant draw / paint by hand except for stick men <most unique one I got so far (I think) <my favorite so far please c/r and give tips :>
Ryu one looks the best in my opinion. Try to stop using all texts for now, wrong style of text will drag the tag down a whole lot, text is optional. Colours, try to pick vibrant and bright colours, try to make your tag as colourful as possible, use less monotonous colours. Your tags lacks a light source, add one in using a white soft brush, when you get better, learn how to use dodge and burn tool. Spend more time on low moderate tutorials rather than the very beginner ones, that was how I improved. Keep it up.
