If the bottom one is meant for an actual playable AoS, then I guess it is good enough. But for showcase purposes, I think you should've placed either a lot more crystals than that or use snowy Spires instead. Fog for both maps looks nice, but I enjoy white fog with snowy regions.
The first one is good, but has some annoyances in it; such as the little houses and the rocky tiles on the surface of the plateu. You should have also placed more Environment doodads and definately could have created a dense forest and a waterfall to make it look more... elvish.
Your flaw is that you fear to use too many doodads. As long as you place the doodads in good spots, it will be good to place over a hundred doodads in one screenshot. So feel free and place a bundle of dooads together that also go together. Like a forest of trees with shrubs, rocks, logs, river rushes(tinted darker) and bushes. Those would look good together. And never forget to make hill variation. It will make your terrain look real and won't look so boring. Never make pointy hills! EVER! Keep them smooth, even the mountains. Sometimes mountains are excused from being pointy, but it is highly recommended that you keep them looking smooth and tall.
