hey Poju, very nice work so far. and what a nice hobby, I wouldn’t mind being there in the pic 
I have a couple of suggestions, I made a repaint of your pic in PS to show you.
click image for larger view

it’s mainly some DOF(gaussian in PS) to the sky and sea, to put you and your ‘fishTools’ in focus. as that’s the main importance in the scene, at least for me.
also sharpened up your face a little to add to that effect.
I also added a slightly blue tint to the image(in PS, colorBalance, midtones: -40, -20, +50) to make it a little calmer and more relaxing. as that’s seams to be one of your hobby to 
ofcourse nothing you have to do if you don’t wan’t to, just ideas. good work so far,
take care
