Is it still worth it ?

I quit selling themes on TF one year ago, I had one “own” theme, and a lot more created in partnership with my “boss”. But then I quit that job, had a large project and absolutely no time to invest in TF.
Now I have some more time by my side, and I think to give it one more try and create a theme to sell here.
Is it still worth it ?
Is it harder to get on the market now ? Are sales really down ?
Thanks !
