The title "Blue" is just the right word for this piece, I never thought that blue could look this good. The shapes and the stocks is a perfect contrast against the deep, blue background. There is so much details in this piece, so it never gets booring to look at! When I first saw this piece I didn't like the pink at all, but now after looking at it for a while, I realize that the pink makes this piece much more entertaining.
You have really catched the ocean-feeling, with the bubbles and the excellent background, and that is why I love this piece so much. I really tried to find something less good with this piece, but I didn't. Again, great job!
I really love your pieces they are all vibrant and creative. The colors really contrast greatly against one another. The use of blue as your background color really ties in well with the concept of it being an ocean. The stingray as your focal point is very interesting because it is as if it is flying into the paint. The use of other marine life is interesting as well and really do add to the life of the piece, as well as the color.
A slight thing that bothers me is that all of the action is concentrated into one area, which leaves some of the other areas barren, such as the bottom left of the piece. Maybe you could add something else there to fill the void, so that the entire piece can be balanced in terms of activity.
Overall, I think this piece is great and would look spectacular as a wall print. Keep up the awesome work Archan.
