Thanks man, Im the art guy, I can tell you personally there was no intended sunset there, I put a brighter color over the horizon so silhouettes of the background looks "clearer". As much as I wanted to take credit for such a brilliant artistic choice, I was simply pushing buttons and see what works like a dumdum.
For the size problem, it was not intended either, I wasn't able to completely explore modelling the creatures since I had 24 hours and a whole lotta art to fill in, so the size might be all over the place, the headstone looks 7ft tall if you're standing on the hills. I guess we are just burying giants after all.
I have to personally apologize for the stamina system. I messed up, man. I am also half of the code guy.
