So you've made your escape from Moonlight to this little island have you? Let's take a little look then shall we?
This is a really nice vignette, and I think you've done a great job with it. I appreciate how hard it is to do landscaping, as I have a lot of trouble with it myself, and it is even harder to do something good in such a small space. I think you've pulled off the slope of a beach really well, there aren't any weird bumps that don't fit, so all good there. Yes, I must say you've handled the landscaping nicely. As a couple of others have mentioned, the transition between the land and sea is a little abrupt, but that is hard to avoid in such a small model. It is to bad you don't have any light blue plates, as I think that would have given the sea a bit more texture. The sea still looks fine without them though, and the breaking waves make up for a lack of varying colour. That technique you have used for the incoming waves is awesome! Very inventive use of parts, and they fit in well and give a nice effect.
Also to do with landscaping, I really like the curve of the trees; that adds a certain something to the overall model, and contrasts with the ridges of the sand. Very nice. The use of loose plates for dug up sand is cool as well.
Now on to the minfigs. You've got the faces just right I feel; that terrified face on the man sure is a useful one! There is one improvement I think could be made on this, and that is the placement of the bearded man. He seems far to lifeless for a bloodthirsty pirate. Try putting him in some sort of pose, for example, digging up the sand or heaving it over on top of the buried soldier. As it is, it does look fine, but a little more life would do him some good. He looks a little dull just standing there with a shovel, if you get what I mean.
As for the woman, I think she is positioned perfectly. It looks like she is straining against her bonds, desperately trying to pull free and save her dear soldier. That or run away.
That's the feeling I get, and all of that is just from a little bend in the knees! So as you can see, even a little bit of movement is very effective. I also find it amusing how she seems to be leaning away from the ant that she is apparently staring at in horror, not aware that there is another one coming at her on the other side.
That is really cool.
Well that's about all I have to say, I hope you find something helpful in there. You've done a terrific job, and should be very pleased with yourself.
