Well. 
Say what, I'll be honest ;] 
I don't like the silhouette
of a woman there. I understand perfectly what you try to show in this picture, however... please forgive me for saying so, but she looks little funny;] 
Hmm... on the other hand Harey is an essential character in 'Solaris', so thats naturally good thing to show her. 
Never the less, I think it is a good done job, especially if you created this using Star Office;] (I'm a Corel enthusiast, full respect anyway !!!).
I think the cover carries a positive climax, it also seems to have an element of some old-time moods in it. It is definitiely good (still a bit funny ;] ). 
And now to business - MAN YOU'RE A GENIUS !!! These images of Solaris' ocean are greeeeeeeeeeeeat !!! 
I've read through you're website (pure pleasure, You happen to live in a very beatifull town (as the photos show), and no doubt you're a man of many talents and various interests 

) and have noticed the parts about Tarkovski's solaris (great photos, jeeezz... it seems like word "great" keeps returning, heh). 
I regret I don't speak german at all - therefore I can't understand all of Your website's content. However I understood that you've created the Solaris' images with Bryce 5. Never heard of it (the program). Is it open source?  
Back to the ocean's images - I especially like (love) the red one. Congratulations. 
Ok, I'll send more compliments later :]. Greetings from Poland.
