If you really want to succeed with your artwork you need to build a following. Start signing up to the big art sites like Art Station, post your art here on the gallery too. Maybe even start up a Youtube channel showing off your work and maybe even giving tips and tricks to those who may not be at your level. Challenge yourself to create something weekly and put it out for others to see. Start networking with those who are in your field.
You say “whatever force was driving me was no longer there”. This may be because you were working solely off motivation. If you work only when you’re motivated you’ll definitely feel like that. If you had a following of people expecting to see new art work from you on a weekly or even monthly basis you now have a reason to continue creating. Don’t overwhelm yourself and put excess pressure, but sometimes things like that can make a different in keeping the momentum going.
