Very cool. The wrap & and colors are great. I like the overall feel of the design and the thought behind it... looks like a fun concept.
I think the design may warrant diff inlays? I see that the kokopelli symbol is not set in stone but easily recognizable...
Could maybe do some progression with the denoms?
I like the rolling edge and it would be better in light of the above to have them tied together but slightly diff on each.
You'll have to find out how they'll do the printing b/c if it's similar to NJ you'll have to take that into account which the current mock doesn't IMO... they'll be some randomness so they all won't be the same in regards to horiz. & vertical alignment.
If that edge design will work another set could have spirals.
The symbol made me think of the font Jokerman... might be some shapes in there to play with... but also more relevant was Mini Pics Red Rock if you'd consider other characters for other denoms?? The font charming symbols? made me wonder if there were other similar symbols of good fortune that may fit in with the theme... is the geko a sign of good luck? Is the symbol with the same wrap too repetitive? Thats what made me thinking of other options... maybe not??
Just some first thoughts... if I come up with others I'll serve 'em up.
Look forward to seeing this progress _and_ your review of the samples.
