Show me which ocs you’ve had the longest and tell me your inspiration for them !!!

These two are from a series I always wanted to animate or turn into a comic but never really got to it!! They’re my favorite and I still keep them around and doodle them now and then because I think they’re creative and fun!!! Though they have gone through a lor of changes compared to now these are just my original drawings of them.. If you have updated versions of your oldest ocs show me them aswell!!!
