I've just spent two minutes scrolling back and forth from your critiques to the fish pics and trying to see what you're seeing. Definitely a learning curve for me! I can't understand the rays. How can you tell how many there are? It looks to me like there are at least 16 on that plakat but I guess I'm mistaking pattern for rays. Which are the real rays?
Here's another fish up for critiquing:
All his fins are pretty uneven and wonky, and I don't know what's going on with the flat caudal. His topline and vents are pretty good though I think.
