first:
Ever done a doubleheight-pixel pic? I've done a few before.. You could get a 640x200 mode (mode 2) on CPC, though it was monochrome.. EGA had a 640x350x16colors mode, and you could tweak the VGA to get 640x350x256colors
(X-Men did it). I think you could also get a few variants of the mode on Amiga.
Anyway, if you want something else odd to try..

my effort at improving my usage of doubleheight pixels. The facial expression was the hardest to get right -- it was difficult even showing that it was a face! It was done restricted to the non-AGA Amiga 'master-palette', which is 16*** RGB - I found i couldn't meaningfully add any more colors after the count reached 114, so that is the colorcount ( I was trying to add as many as I could).
Edit: Thanks Helm!
I hope the board will let me post in future

And to the main subject!

These Icons are for my Jormungand project, which is a port of the OHRRPGCE RPG construction engine to Python.
More Info Herethese icons are in order,
Fire Water Wind Earth Lightning Poison Light Dark

** This is vague.
*** Or Name.
Crits on any of them would be great, but especially the ones i think are currently vague!
They are marked **.
The set is not complete either - I need an icon for every visibly-accessible idea in OHRRPGCE. I have ideas on what to do for these, if you know the engine you might have better ideas, tell me in that case too!
