Can someone help me with this sentence?

Quelquefois, je me suis senti inadéquate parce que je n'ai pas acquis beaucoup d'expérience en dessin.

my teacher circled "n'ai pas" i do not know what is wrong with it:(

je me suis sentie inadéquate...
(assuming Megan is a feminine name).

Can you review the tenses you have learned and see which one works best for
"parce que je n'ai.."?
so maybe imperfect?

Je n'avais pas..?
This ("plus-que-parfait") sounds OK to me.

I hope you chose it based on some logical thinking and not a wild guess.

When looking for tenses, consider the time line:
(Past)->had not acquired->felt inadequate->(present)
