Well i think a 3.5 is a bit to low.

Those happy-colored-borders were quite hard .. its not possible to made a atmospheric-picture out of it like the caradhras-one, and its quit hard to paint a animal like this hyena(well, i know, the hind legs has to be smaller) ;(
And well, i havent cut those legs of to make my live easier, but combined it quite good with the black part is opposite.
And also, i think i did well with those purple something, cause i made a hose out of and so i repeat the upper-structure in a new way. And well, i didnt forget a litttle flower. ;)

You actually started a source for the river I started a few tile to the right. Let's see how it develops :)

That is one evolutionary freak of nature! Looks great :-)
