I love the tone you set and representing the characters with different sets of nails is an extremely charming and thematic way to sell me on you game.
I agree with the other comment, the biggest snag I encountered reading the character sheet was that I was unsure of how many dice to roll for any given stat! I would love to see those numbers assigned for me or simply give me a total pool of stats to assign myself (My rule of thumb is 18 total divided among all 6 stats for Trash to Treasure). I think setting them up for me feels a little more in line with the usual Havoc Engine pre-gen character style.
I'd also love to see some little tidbits that help me settle myself in the characters, the name's are excellent, but some titles or a single line of text that gives me a vague personality to jump off of in combination with their stats would really help me dive into play once I pick up their sheet.
All in all, an excellent read!
