I was smurfin' around on this site Xigbar gave me that has a bunch of tutorials...and I decided to take a wack at a few. Here's the first... And the last... I might have messed up something in the tutorials...but oh well... CnC? (my kingdom for one review? :()
Well, the first one is great, but maybe add a light source wouldn´t kill you, good job on the first one ^^. But the last one... Well... It looks somehow plain and somewhat bizzare, furthermore, is only a background maded of smudging, and too if you want add a light source. I suggesting you downloading some CD4, they are great and useful.
I likes alots Ris, on the second one though you need to erase the filter or whatever around teh top of the render cause it makes it look sloppy. I think that you should sharpen them both and add a lighting source to it. And give some good flow. But your text use is very well done. Kudos.
