wouldn't be a bad idea :3

Perhaps it wouldn't! !
If I do make more ill make sure they are freeee

just make sure to keep an eye for people who might take advantage of it. Never know when someone might use it for profit.

Can you make the sai or psd file available for download? So people can use the layers? You can also make them in layers for diff tails, ears etc.
Make an account in a file sharing site like Dropbox. You can link to them :)

Its sweet of you to make them free. You could always make some pay to use.  waitress has a very popular pay to use base which a lot of people are using.

Also, you need to put your prices up :P
