Really nice piece of art, indeed. I like the idea - very lovely and cheerful.
I suppose you wanted to make the sea dog (you don't mind if I call it like that?) the most outstanding part of the picture - and you achieved that goal on 100% but from the other side there's underwater stones either- I'll mention them down to the text. But Let's get to the point
+SO - the strongest part of this picture is - very pleasurable composition, The location of objects looks smooth and harmonical to the eyes
+ Anatomy. Even if the dog looks like fantasy creature - it still has good proportions and I don't find any negative features there. As for a dolphin - it's also drawn very well..the only feature that disturbs me - this is it's tail - looks a bit unnatural, dolphins have horizonal-turned tails, the tail drawn here is more fits for usual fish. But this is really nothing compared to the rest of the well-drawn characters.
- The Lightning. I really like how you reflected the sunbeams of water surface on the back of the dolphin. And it seams that the sun beams is really strong on the picture. But it's reflection on characters doesn't really depicts the reality - as a result the picture lacks its depth and the characters looks a bit flat under such strong sun. Remember - the water is completely different enviroment than the air - the deeper you go from the surface the darker colour becomes - I see this on the background but characters seem to live separate from this statement. Don't be afraid to add some contrast and make deeper shadows next time - and it makes your work looks much realistic. (but, of course, don't overdo with it either
) The dog also needs the sunbeams on its back - otherwise it separates even more from the whole picture. Look at this tiger for example nynightclubbing.com/wp-content…
It also has fur but there are sunbeams on it anyway.
- Detailing. Don't get me wrong - I have nothing to say about detailing of the dog - other than that is great) But - again - the other components looks separate and flat compared to this great dog
When you make so much detailing on one object - don't forget about the others - this is the story about the dolphin and the sea dog together not just the dog alone
as I said - the darker shadows and contrast could help here
And seaweeds - they are on the front of the picture, so they also need more detailing to bring depth to the picture.
...and this is it) As I said - the picture looks nice in common. Work with minuses and you'll be even much closer to becoming a great artist)
I've tryed to be less subjective and more objective in my critique, relying on artistic point of view rather than my own.
I'm still learning but I hope this critique was somehow helpfull to you
