Crankshaft's Sketchbook

I like it although the tree growing there doesn't necessarily make sense.

I'm guessing there's some sort of idea behind the tree, but like Banji said it looks a bit out of place being old and gnarly in a squeaky clean new built city (as it looks, so far). If the city is meant to look new, maybe a fountain with some pruned bushes and flowers around it would be more likely? And they'd hide less of the structures in the background. But again, if there's a story behind the tree you should keep it. Though, you could try making it half the size of something? Like here was this important old tree but a new and big city grew up around it... (Tree roots overgrowing the city would only make sense if you intend to make the city look old and crumbled in the end... but perhaps you do!)
