I like the direction you're heading with this (and the design itself), but I think it still needs a little bit of work. Maybe add a couple of the things you were thinking of. :)
Oh, one question...why is there a ladder going into one cube? I know it's to give the impression of a swimming pool kind of thing, but it seems strange since it's the only one with it.
added it only once, but you're right that there should be ten in this case... might a bit too busy, when there are ten of them haha.. but thanks for the comment. I shall experiment a bit with it..
hmm, the grey i used as the shirt color isn't an actual shirt color.
it's a in-between, so i have to lighten it a bit to the silver grey color. hopefully the white lines won't fade away...
but i can add another color :-) to darken them again... yesss!
probably could spend hours on adding those 3 extra colors, but i like the simplicity of the colors i've used till now.. maybe i could upgrade the water a bit...
