Having recently discovered how hard waves are to paint I think you have done a fine job here with the curve of the wave.I particularly like the translucent blue just under the wave. I struggled to get that right but you have got it spot on here.
Nice start! I’ve tried 2 oceans scenes out of books and waves and water are hard to paint! I’m still working on getting that curl right now. it’s not easy ! But keep at it, be patient.
