Sorry, don't have time to go and look individual pictures, so, kinda general advice: take more care with textures. Also, from what I've seen on thumbnails, more care of what the picture shows. That is, put something in focus, do not create kinda general picture. there is a nice tut out there on composition, but I cannot find the link. (Isn't it always the case? :-)) AgentSmith put a link to a "how to create a good landscape" tutorial in spotlight link of the week some time ago, try to find it. As for inspiration ... well, read, listen to music, see films, see old masters, take a walk ... you'll certainly find something that will strike your fancy and that you can try to recreate in Bryce. Or improve on the subject. :-) Hope this helps.
