tips for zuco(wallpaper):
more grass...it just seems to start...make it so that it is nice and thick at the bottom so you cant see where different blades start
reduce the strength of the plastic wrapper if thats what it is... nice effect though

for tect, there is a button saying "T" in your left toolbar
i would show you some effects, but im not sure what sort you would want...
if you think im being harsh, im sorry...for every picture posted in this thread, i will make comments like this to try and help you improve
