the first thing that comes to my mind is how you did this ? I dont think I could ever paint like this but I would really like to !
So basicly I dont mind if you could have shown step by step how you did this work !!!!!!!!!!!!!!! And of course with what program and what brushes etc
only one thing that comes to mind if I have to crit something is that whatever the brush is that you are using should not be used all over the place, forinstance on the right side there is opening where you see the sky (?) I would have used another smooth paintbrush for that area as well the edges of that gate entrance is not very symmetrical and neat, then again you said its a speedpainting, but I think even in speed painting you have to choose few focus points that looks near finish and such, kind of tieing up the remaining chaosness and looseness of the image
look I dont know why I love you I just do
