online photoshop tutorials

[leeb]

hi all,

had a bit of a hunt about, but not found quite what i am looking for.

i want to edit my portrait work, and make things that are a whole lot different, and that really jump out at you with the 'wow' factor.

i know my way around photoshop, just wondered if anyone could advise of any online resources which have step by step ways of creating certain effects, other than your standard pencil scetch etc.

Thanks a lot

lee
