I'll be doing them on tegaki-e so they will have a set size already. You're choices are as follows:
$1 plain lineart
$3 colored image
$4 elaborate image
add $1 for every bonus lineart character
add $2 for every bonus colored character
Can only accept paypal, please send money as gift if you please. Paypal is: firstname.lastname@example.org
Haven't got too many examples just yet but I'll post what I have so far.
