Thank you Killersquid and thank you RJS.
Suggestion about Ogryn Flesh is a good one indeed. That's why I intend to buy it.. (and honestly- without your post I wouldn't probably bother to).
And about bases..
Visit to Egypt has taken it's toll. I was impressed and taken aback by Sahara desert and I wanted to make an army that would operate on such land. The problem is that when you venture into the desert there is nothing to look at there- no grass, no rocks, no nothing (apart from piles/fields of garbage near main roads).
Desert is what it is- desert.
And that is why I did those bases to look how they look. Most people who have seen them 'live' like them (or like me and lie in the face
Long time ago I did bases that have colored edges but that didn't work (as you play paint scratches off even if you use ardcoat vanish).
Added few days later:
I've used Ogryn Flesh on skin and it doesn't look well.
Doh, still fighting.
