Looking solid dude. I'm a sucker for a blue-orange compliment palette, so I really like what you did with this one. I'm also digging the vignetting effect you achieved around the outsides of the frame to draw you in more, and your use of birds for scale is much better than the cliched two or three birds here and there that some people use. Overall I think the painting is working and reading pretty well, but there are a few things I think you could tweak to make it even stronger.

The first thing I noticed is how wide the composition is. The panorama effect works really well with some pieces, but it can sometimes be difficult to keep the visual interest consistent throughout the entire landscape when something is extra wide. My main issue with how wide it is is the negative space between your figures and that first tower. Because the space is close to center, and because it's wide open without much anything there, my eye keeps getting drawn there. I might try to close that part up a bit and bring the figures closer.

The other thing I noticed was the painted/unfinished look of the figures on the left. In some paintings it works perfectly fine, but you've done such a good job with the landscape, they almost stand out a little too much.

A few simple tweaks I might try are blending the gradations in value out a little more, as well as making sure the flat tones aren't just one value all the way across. To create form and dimension, you need a gradation. So, by simply gradating a bit more, and blending some, you could make them fit a little better. Also, as the focus is the the landscape, I might also try giving them a slight blur.

If you click here, I did a quick Photoshop tweak to tighten up the composition as well as blur the figures a tad. I hope you don't mind, but I figured it would be an easy way to get my idea across in addition to typing it.

Also, by tightening it up and changing the overall aspect ratio, you can achieve a much more cinematic feel to the piece, and I find that adding the anamorphic black bars on the top and bottom of a piece like this also help the dramatic/cinematic feel.

Overall, great job bud, and in either case, the work is solid. The atmosphere you've achieved here is quite good. Take care and good luck on your future endeavors!
