Firstly, I'm new not only to this forum but also the DE army, so I'm posting here the very beginnings of my new army for comments, (friendly) criticism, and advice. I hope that it's ok to post pictures of my models in this section since it's not intended to be a painting log - rather, it's for discussion.
I had some old DE from the 3rd edition of 40k and I've reinforced these with more purchased from eBay. I know a lot of people don't like these much but I quite like them. I thought it may be the helmets/heads that look wrong though, so I tried replacing mine with dark elf warrior heads. And I also tried something more like a 'modern' colour scheme (though since I'm not an accomplished painter it was basically black with dry brushed green).
Afraid the pictures I have aren't the best, not helped by the fact that I'd (gloss) varnished these before I took them, but I think they suffice to give the general idea.
(Sorry, wasn't able to work out how to thumbnail/gallery these either, despite Local_Ork's thread - I couldn't find where to get a thumbnail url from - but I hope they're not too large.)
I think with future ones I'll try leaving off the spikes on the shoulders. I did also try trimming the shoulder pads down on one, but decided that was too much effort and I'm not bothered by them.
I know they're not the prettiest - I only aspire to presentable table top quality - but I'd welcome opinions, particularly on whether I should keep using dark elf heads (which look a bit pixie-like to me) or use the original dark eldar helmets. I keep going back nad forth on that one...
