Even though I'm not a photographer myself and I'm not very familiar with all the options in this genre of "scenery photographing". I can tell that you know how to choose your frame and to make the most out of the light and shadow in the scenery you see . 

It's really cute how you take pictures that cut objects or make the obvious look so pretty and special like in here 

I don't know if you could choose another angle in your most recent art-piece,   if I were you I would have gone to where the palm tree is, I see that you already have three main parts of 'kinda wild nature', 'train', 'classic castle', if you place the nature at the lower third, then the train in the middle and the castle and clouds which are sooo clasic and fancy get the biggest higher third part of the picture- it would have shouted out to the eye of the people who see it. Clear cuts from three different worlds. 

From what I see you have the gift of being able to bring out a concept you think of in all your artworks. You decide to choose a main color and you use it for mmost of your drawing, this is kind of nice and you should continue with that. You have a soul in every one of your art pieces, amazing. 

What I think you need to improve is the way the lighting you make up for the background effects the character. In this paint for example  you could have used the beautiful blue in the background. It looks out of place that the character has its own way of lighting itself ignoring the background almost completely. 

In the artwork you posted here you colored the character and even though the background doesnt have a specific source of light its obvious that the upper part is darker and the lower part is lighter, it's not effecting the character at all. The overall 'drama' in the artwork lose someyhing if you get what I mean
