Ah. There's something I like. Sure, it could use some more detail in the distance (on the mountains, the water, the distant land, the sun and flares, and what-have-you), but I really like how this one turned out. The foreground is fantastic in comparison to the previous images... This is much better. Especially the sky.
It feels so much fuller this time. Now, provided that you can get the distant background items to be more detailed (I know they're blurred, and I like that, but a little more realism is in order, I think... try some rotoscopy and see what happens), I think I might be able to accept this as a pass. You've proved that you have some solid capability... you're almost there.
If you can show me just one detailed mountain, lake, and tree - I think I can accept you on to the team. Sure, there are a couple more kinks to work out, but judging by how well you adapted to my previous requests, I'd say that won't take too long. My suggestion, again, is to try some rotoscopy. Find a nice picture of a mountain, a tree, and a lake, paste them into flash, and draw on a layer on top of them, using the actual objects as references. You can get much better detail and realism that way. Plus I love the effect of rotoscopy =D
No need to put them into a background, I just need to see that you're able to get the realism I want. If you just put them on a white background I'd be fine with that.
As long as that looks good, I think you could pass (sorry if it seems like it's been a rediculously long process - I'm just looking for a level that I think was a little higher than you had aimed for before. I think it's within your reach, though).
Good luck. :D
