I am considering making an art shop, but idk what my art is worth

~

Here are some examples from oldest to most recent:

2 nd piece I've ever made (1 hour, 7 layers, went for 50 k)

3 rd (2.5 hours, 15+ layers, went for 10 k)

4 th (2.5 hours, 15+ layers, went for 35 k)

5 th (40 mins, 4 layers, the auction hasn't ended yet )

6 th (3.5 hours, 25+ layers, the auction hasn't ended yet)

And my most recent (2.5 hours, 30+ layers, idk if I will sell it or auction it)

50k maybe? Def tier 4
