Congratulations Marina!
I hope you do not mind if I tell you that this lovely portrait does not feel like an oil painting to me. Actually, I thought it was a pastel painting when I first saw the picture (I know you wanted to avoid it to look like a pastel but the colors do not make us think of a simple drawing at first!).
This is a typical case where you do not know if you should call a piece a "painting" or if you should call it a "drawing"...
We can see some strokes in the close-ups so it is still a drawing, but how well mastered!
Anyway, I am very glad to see your current works. Please keep posting
Sincerely,
Karine
