well, Random Curiousity screencapped an invitation episode of Clannad yesterday, and kinda wanted to make a new siggie, so used a screencap of the Clannad invitation episode to make a new siggie last night xD I used this picture
but it still wasn't easy to work with screencaps

cuz you need to get rid of the blocks you see, the color and overall quality is not so high and go on and on xD but I still tried, and spent a little more time then usual on it (like about an hour xD ) and this is the result
now for a screencap sig I like the outcome of it, but compared to some other sigs it's not that great, but maybe I'll make another siggie today
Update ::
updated version for someone who wanted the sig with the Natsu Shoujo border...
