Wow, these are great. I like the ships particularly, keep up the good work!

Good use of lighting and colour, especially on the entrails!

Having the smoke travelling from right to left is actually what I meant, it's our eye that will travel from left to right following the smoke until we reach the structure. Sorry if I didn't explain that very well before!

Excellent work on the collar! How severe is the colour variation between monitors? If it's not bad enough to completely change the mood of the piece then I wouldn't worry too much about it, this is a great painting!

Good stuff, the middle one's my favourite. I used to be really into matte painting but I got fed up with having to spend so long on tiiiiiiiiny details! Have you seen Dusso's gnomon dvd's? That man has insane skills.

The improvements are good so far but I think the legs are a bit too bright and dominant. Just some subtle shading on her thighs with some bluey tones should fix this. The clouds on the wall are great!

Nice colour work, I like the warmth of the grass in the forground although I do agree that the sea is over-saturated. I think the clouds could do with a little more definition to help create a better sense of depth to the sky, also the seagull on the left is getting overpowered by the bright cloud behind it. Try simply moving it over to ...

I would try adding some low clouds/smoke running from left to right to help draw the eye across the image. This will give the impression of wind, which will enhance the feeling of an exterior environment. Some dark areas of junk in the forground will help create depth too. The birds are a great touch.
