Ok, Oktorok Shadows on the todo list.
Working on day and night.
Why is the number of rupees running into the bomb icon (bombs are also too close to arrows)? Needs more spacing. Other than that and the octorock shadow you've already got on your to-do list, it looks pretty good. I do agree with Niek though; it is a little hard to see, but I don't think it's all that bad. Light sources would help (torches, lamps, camp fires, etc).
And did you just recently add the shadows to the big trees? I like the shadows; looks great.
EDIT:
Some more stuff related to my Zelda project:
Working on the HUD. I expect it to change more as I figure out Link's actions and controls.
And here is a map of the main room. This is basically the equivalent of the overworld of other Zelda games. I don't really care to explain what you're looking at though (color significance, etc).
