Hi Eunan welcome along
The picture itself is ok but there is a little to much going on in the foreground
You should try and get something simple in the f/ground to lead to into the shot
On the uploading side of things try this link
Hi Eunan, I would straight the horizon and crop a bit of the left part and the top. That will balance the image. Also look after the cyan sky. It is a bit strong and unnatural. ( ; cheers Madeleine
