ouch, this perspective exists and was used in a few old school games. You haven't done a bad job, but I have to say the angle is one of the most disgusting angles ever to make it to video games, if not the most! I don't get why the higher blocks become a darker colour. The green enemy looks like he is on the wrong angle. The textures all seem pretty much the same with just different colours. So far I like the waterfall most, I would change the angle before continuing on this, as it is a fair bit sickening!
