Very nice and interesting looking icons Ivan

I have some other ways you could use xaralx to get that embossed look using the bitmap trace and bevel tools, and even the gel'd "E" look using the freehand brush, and bevel tools
I'll do some later and show in another post, so as not to intrude on this one.

Showfoto also has some really nice filter effects to achieve those results... as well as GraphicsMagick
