awesome tut, great outcome if you put a bit of effort into it, i've made a few but this is the one i was happiest with (in the end i added the b/w gradient map to see how it looked and liked it so i feel im not copying exactly xD) its really well written and lots of fun to do :]
Currently in a pickle about that since my hosting is down and I can't rehost it atlm since I'm not at home. I sent you my other Lp tutorial though and I'll send this one afterwards when I get back home again, no extra charge
