The tgrass looks very good, The tower was about to look good, and the rest of the hill is unfinished.

Yes, you obviously know what you're doing with the palette. Excellent in that respect. But unfinished it is. Glad if I inspired.

I'd agree with HMC.  The right side of the island is devoid of anything, whereas the left side is teeming with detail.  Even making the outline of the right side more detailed would give some sense of finality to this piece.  Right now, the right side of the island is nothing but a blob.  Also, where is the reflection on the right side of the lighthouse coming from, if the moon is in back of it?  I don't see any effect of the moonlight on the structure. 

From what I see now, you demonstrate a pretty full mastery of the pallette, especially on the left side of the island.  I think you need to juice that right side up with some detail and tweak it a bit.

The B.O.B: I'll consider adding more detail to the background but I personally like how the yellow looks, so I am not going to change it. Also, thanks.

HMC: Care to explain?

It feels very unfinished.

looks pretty cool and it does that ega building of helm's justice....My only crits are just that of the color bieng used. I understand the point of the palette bieng chosen, but for some reason, the yellow seems out of place. I don't know why, must just be me. Maybe if it were replaced with white? Either way, I like how you show where the line breaks off from the sky, by just showing a slight reflection in the water. I love suttle "bull-spit" like that. Oh and maybe you could incorporate some dark clouds to give the background some more character to it. Crits aside, I like it none the less.
