well yeah abstract and all, but you did the style pretty good by having a kind of order and sense to it - the planet appears to be almost coming out of or being connect to the what's-it-called, the walls at the front provide that kind of boundary between the "dream world", let's call it, however after that it's not that really great and tasteful style, but rather a bunch of rather normal looking hills, except that they're obviously not actual real ones. the chessboard is a pretty average addition - it's not really majorly adding to anything, but its also not really out of place or anything, it provides a bit of a point of a focus. i'm guessing the two gearwheels have some place in the picture.
what i'd do is just had a more normal landscape and scene in general - if you have like a general backdrop of a rather normal place, with good terraining on it, and then stuff like you have there, it looks a hell of a lot more interesting and effective than just everything being abstract. really good abstract things will usually have a balance of the two, and often each element by itself makes complete sense. so, for example, if the chessboard had some more different figurines, maybe even just white/black blocks, that are set up in spots, it'd make sense by itself, but then you throw it in there and it's part of the whole abstract picture.
what bothers me the most is the rather unshaped terrain, it looks quite bad if you look at that part of it. that's why, as i said, i'd make that better and all, just to actually add to the abstract part.
