I think you should work on the lighting and overall feel to the image, right now it looks like a collage of photos, so i suggest trying to match colours and create lighting from only one direction.

ponti55 is right. You would do well to take the advice because you could have a GREAT image with a few changes! Good luck!

I think more visual clues of ginormity such as a sailor and trees would add clarity and drama. Also, the reflection in the water should be the same size as the original, not squished.

nice idea : D.

when its 1 thing that is the size difference it appears as if that one thing is what size has changed... the theme is to make something big, not small, like what youve done with your boat.

i totally agree with ponti. you could create a new colored overlay layer with low opacity so everything on the image gets at least the same tones. kinda like sepia or something

love this

i just want to make the point that making an overlay of a single color will not fix the issue, it will just change the hue of everything here. that isnt a great suggestion. instead match the blue on top with the blue on the bottom, and get rid of the lightning. take that layer, and make some minor levels adjustments, and open hue and saturation on it, select only the blue channel in the hue and saturation and lighten it up a bit and adjust the hue so thats its more of a cyan like you have on the bottom.

nice job
