Well, I told you that I'll write you a critique, so here it is
Vision: Inganna looks simply gorgeous, her outfit is really amazing and perfectly shows the beauty and power of Harmonix transformation. Bars and ribbons highlights the dynamism of her moves under water, waving dress also looks great in the ocean.
Originality: Her Harmonix outfit is original and unique, it suits Inganna pretty well and highlights her beauty.
Technique: Picture was done in a very detailed way, coloring is very impressive. You've used the base, but it was used in my opinion in the best and the most professional way.
Impact: I'm personally very impressed, this picture is magnificent and it's a great pleasure for me to watch it.
To summarise, you did really great job, Inganna looks very beautiful and I love her Harmonix. I wish you more pictures like this
PS: Now I really have problem which of your OC's I love the most
