Generally it looks cool, But try to place those bridges so that they lead the eye throught whole piece. Another thing, you can brind more distance if you refine more the background, right now it looks a bit flat!
Another thing is lasso tool, use it if your need refined shapes!
These are just my advices that can help you to improve))
Ive never used that style,allways just start with a brush and sketch out the rocks ect ect. Im interested in how you get such clean light work,do u lasso in detial and add the light area's using the lasso tool?
Ever thought of making a tut or record how you do it for youtube? i would be interested in it
