It's two things for me. First is the material, which seems a bit thin. I find that outside of extreme summer heat I prefer cotton trousers of any kind to be heavier as they will hang and drape better. A nice 10-11 ounce cotton trouser would probably work a lot better, could hold a decent crease, etc. In winter I'd look at moleskins.
Second is the color. Generally speaking I do not like grey chinos. I've yet to see a pair that looked nearly as good as grey wool trousers in a similar color. Chinos to me should be in the stone / khaki / tan / olive range.
