This looks like it belongs to "The Stronghold", the mood is pretty much identical, so is the design of the walls and the weather. Very nice!
If I may ask this, did you use a photograph and layered the walls with it to quickly create a bricks texture or did you make it all by yourself (in that case it seems like a lot of work)? I've often read about the technique to use photographs to fill the voids on elements and to achieve a realistic look in a fast way and have been wondering if I should try that myself as I took many resources of surfaces myself (although for different purposes).
Well, strictly my opinion of course, your method of drawing and coloring architecture looks very realistic and rustic, usually fitting the theme you put it in to. I don't know if you were playing around or not with the stick-blob head figure, but if that is the issue then that's what sort of needs work on. Any other thought for me on this would be the fire, it felt as if were missing a few more flickering sparks of embers. But simply that is me.
Overall I do think that you need not rush with trying to make progress. Just focus on some things from time to time, but make adjustments gradually.
