I can't help but think you're heavily influenced by Billiam Babble's Ink Adventures
Duuuuuude, :D *bashfully embarrassed, but appreciating the support* ;) We all know that I steal all my best ideas from 1980s GW stuff - and Eric's coming from a similar place. I think I may have mentioned this LatD to him because I know we have plenty of fans here of the older styles.
For the benefit of everyone here and for the record I personally believe that Eric's work is slicker than mine and he certainly hybridises the strengths of using a computer with a hand drawn style - which means he's still one of a minority of genuine experimenters, whilst the rest are still fiddling with 3D renders and photographic textures. And then there's a whole bunch of old school types who just draw to paper and scan.
Eric has managed to produce a selection of aesthetically consistent sets of tiles in a remarkably short period of time and I believe that the RPGers and (US/Canadian/UK English speaking ) OSR communities are still catching up.
He's been illustrating some of the new Advanced Fighting Fantasy books - I think(and lots of different things which are French) His figure and character portraits are just fab.
