How many tiles can you use? Because i've found it's good to pick a relativly uniform pattern that tiles really well and use that for your basic tile/s then do some feature tiles you can throw in to give it variation and break it up. Also yeah the style of the rocks on top are totally differant then the ones on the face (though i figure you'll fix that) They appear to be in the background which wacks out your sense of scale.

How were these cliffs formed? Earth quake? Erosion? Artifically? Land slide(ice/mud/soil)? Volcanic? That kind of thing changes the way rocks form, colour, size, density, etc. Your best to just crack out google images and find some real cliffs or cave interiors that mirror the kind of conditions you wish to simulate and work from that. You can only go so far working from other artist's interpretations.

That would be a great project! I'd love to see that. 

Also woops, i couldn't figure out what they were. Hmmm futuristic bright yellow tentacles.  *strokes her chin* How about something more along this line then? I'm just trying to show you afew ways for you to shade them which isn't just banding colours inwards (like you'd started to do earlier). Give them abit of volume and shape! Glad i'm being helpful.



I'm using an online .gif converter and it's making the colours weird out.

If you look at it you'll notice the edit actually has alot less detail. All he did was cut down the number of bubbles and add a light reflection on the outside of the bottle. :]

As an ex obsessive compulsive ditherer. I see some of my own habbits in you.

Dithering works as texture, blending for low colour count (relativly large) projects or where the contrast between shades is relativly low. Also when you dither a dither (eg light blue to medium blue) should not meet a differant dither (medium blue to dark blue) without a reasonable ammount of pure colour in the middle or it doesn't serve to blend at all, just create texture and in this case make it grainy.

The whole point of dithering is to give you access to colours you don't have in your pallet, but don't forget to use the ones you do have!  You have the colours here to do it without or with minimal dithering. :]

Have to run to class but this is the quick edit i did, i hope it's useful. :]

Contrast, watch colour count, make things three dimentional, don't texture at the loss of volume.
