Hey !
I love your concept, the design of the character is really strong !
For your painting you have some proportions issues, especially the left leg who look too small, and the head which is a bit too big.
Dynamique poses are hard to do and you should really use references.
Great work so far ! Keep going
Here's the final render ! i corrected the leg and finished the background. I will start the board of character with her story and different angles of Thaïs.
i will post all soon, here's my artstation and my instagram if you want to follow me
