Which artstyle is more appealing for selling?

Hi everyone!

My main goal with art is sell commissions as a second income, so I’d like some advice in which artstyle is more likely to sell.

My newest drawing is the first one, with more detail shadows and painting and with a thicker lineart.

The second drawing is a bit older, but I used to paint in a more “delicate” way, with thinner lines and lighter colors.

I’m charging the same

What do you guys think?
