Hi Gilles. The photo has a fairly tight composition... I like the fact that the whitecap is positioned to be a focal object... it almost seems like a separate object from the rest of the scene. I also find the sun's position interesting in relation to the wave, the angle of the beach against the edges of the water, and the golden horizons.
Cutesy? I would say that it might possibly verge on cliche, if one agrees that photographs can be as cliched as writing can be. However, even though I've seen beach scenes very similar to this, several times over, I don't usually see such attention to focal objects and their relation to each other... it's generally just a beach scene by the water, with the setting sun and so on... looks pretty, but it's far too wide angled and nothing takes enough stage to bring it out of "postcard" status. I can tell that this wasn't just a snap of a pretty scene, but you considered the objects in front of you and arranged them. That's what makes me think this is a little more than your average beach sunset snap. If a shining sun, warm fluffly clouds, gentle waves, and an inviting portrayal of a scene qualify as cutesy... yes, this is cutesy. That's not a problem on its own, it's just a matter of what you want to do with it.
By the way, where did you take this photo? I happen to live in B.C. as well.
